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).
