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
