A boat takes a total time of 12 hours to travel 105 km upstream and the same distance downstream. The speed of the boat in still water is six times the speed of the current. What is the speed of the boat in still water ? (in km/h)
A boat takes a total time of 8 hours to travel 63 km upstream and the same distance downstream. The speed of the current is 1/8th of the speed of the boat in still water. What is the speed of the boat in still water ? (in km/h)
A boat can travel 9.6 km downstream in 36 min. If speed of the water current is 10% of the speed of the boat in downstream. How much time will boat take to travel 19.2 km upstream.
The difference between downstream speed and upstream speed of boat is 6 km/hr and boat travels 72 km from P to Q (downstream) in 4 hours. Then find the speed of boat in still water?
Upstream of a boat is 12.5 and boat in still water is 20 then distance covered by a boat in 4 hours in downstream?
If a boat travels 18 km more in downstream than in upstream in 3 hr. and if the speed of the Boat in still water is 20 km/hr. find the distance travelled by boat in downstream in 4 hr. ?
If the boat takes the time to travels 60 km upstream is twice the time taken by the boat travels 150 km downstream. The speed of the stream is 20 kmph, then what is the speed of the boat in still water?
Sum of the downstream speed and upstream speed of a boat is 36 Km/h. Speed of the boat in still water is 2 Km/h more than four times the speed of the stream. Find the total time taken by the boat to go 132 Km downstream and 56 Km upstream.
Speed of boat in still water is six times of speed of stream. If boat covers 210 km in upstream in 7 hours, then find the downstream speed of boat?
If Aman can cover 24 km downstream distance in 36 minutes and 18 km upstream distance in 45 minutes, then what is his speed in still water?
A boat which has a speed of 5 km/hr in still water cover 1km upstream path in 15 minutes. How much distance it could cover in 1 hour 45 minute in downstream:–
A boat can cover certain distance in upstream in 16 minutes and the same distance in still water in 12 minutes. Find the time taken by boat to cover same distance in downstream.
A boat travels in upstream. If the speed of boat in upstream is decreased by 40% then it is equal to the speed of current and speed of boat in still water is given as 240 km/hr, then find upstream speed of boat? (In km/hr).
A boat covers 192 km in upstream in 6 hours. If speed of boat in still water is 200% more than speed of stream, then find time taken by boat to cover 240 km in downstream.
Speed of boat in still water is twice the speed of stream and difference between upstream and downstream speed of boat is 8 km/hours. Find total time taken by boat to cover 48 km distance in downstream and 32 km distance in upstream?
Speed of a motor boat in still water is 18 kmph. If the motor boat travels 90 km along the stream in 3 hours, then find the time taken by the motor boat to cover the same distance against the stream?
Upstream speed of a boat is 62 ½ % of downstream speed of that boat and boat takes 1.5 hours more to cover a distance of 65 km in upstream than that in still water. Find speed of stream?
Speed of a boat in still water is 3.5 km/hr. If the time taken by boat to cover a certain distance in upstream is 250% of the same distance cover in downstream, then find the speed of the stream?

Ratio between time taken to cover same distance in upstream to downstream is 2 : 1. If speed of stream is 4 km/hr, then find time taken to cover 48km in upstream?
A boat takes 1/120 D hours more to cover a certain distance in upstream than in downstream. If speed of boat in downstream in 30 km/h. Find speed of boat in upstream? D = Distance in upstream = Distance in downstream

The speed of boat A in still water is 4 times the speed of stream and covers 24 km upstream in 8 hours. If the speed of boat B in still water is 2 kmph more than the speed of boat A in downstream, then find the time (in minutes) taken by boat B to cover the same distance in upstream.
The upstream speed of a boat is half of the downstream speed of the boat. If in still water the boat covers 72 km in four hours, then find the speed of the stream (in km/hr)
The speed of boat in still water is double the speed of stream. If the boat travel a distance of 120 km downstream in 8 hours and after that engine of the boat breakdowns and distance (D) covered by boat at the speed of stream. If total time taken by boat to cover the (120 + D) km distance is 9 hours, then find D.
A boat can cover 180 km in still water in five hours. If the speed of the current is 25% of the speed of the boat in still water, then find how much distance (in km) the boat covers in four hours downstream.
A boat covers (D+30) km downstream in T hours and the same boat covers D km upstream in (T+5) hours. If the speed of the boat in still water is 15 km/h, then find the speed of the stream (in km/hr).
The time taken by a boat to cover 1.2D km upstream is two times of the time taken by the boat to cover D km downstream. If the difference between upstream and downstream speed of the boat is 6 km/hr, then find the speed of the boat in still water?
The time taken by a boat to cover 120 km upstream in 15 hours and the boat can cover X km downstream in 12 hours. If the speed of the boat in still water and the speed of the current are in the ratio of 5:1, respectively, then find X.
The speed of a boat in still water is 14.4 km/hr and the ratio of downstream to upstream speed of the boat is 3:1 respectively. Find the time taken by the boat to cover 216 km downstream (in hours).
The time taken by a boat to cover 40 km upstream is equal to the time taken by the boat to cover 60 km downstream. If the speed of the stream is 2 km/h, find the downstream speed of the boat (in km/h).
