Practice Boat and Stream Practice Questions with Detailed Solutions – Level 2

A motorboat covers 48 km downstream in 3 hours and 36 km upstream in 4 hours. What is the speed of the stream?

Ravi rows a boat at 15 km/h in still water. The river flows at 3 km/h. How long will he take to go 36 km downstream and come back to the starting point?

The speed of a boat in still water is 10 km/h and the speed of the current is 2 km/h. For the same distance, what is the ratio of the time taken upstream to the time taken downstream?

A man can row at 7 km/h in still water. He takes 7 hours to row to a place 24 km away and return. What is the speed of the stream?

A boat whose speed in still water is 12 km/h goes downstream from A to B and returns to A. If the stream flows at 4 km/h, what is the average speed of the boat for the whole journey?

A boatman takes twice as long to row a certain distance upstream as to row the same distance downstream. If the speed of the stream is 2.5 km/h, what is the speed of the boat in still water?

A boat's downstream speed is 20 km/h and its upstream speed is 12 km/h. How long will the boat take to cover 64 km in still water?

A boat covers a certain distance downstream in 4 hours and returns the same distance upstream in 6 hours. If the speed of the stream is 3 km/h, what is the distance covered one way?

Meena rows at 9 km/h in still water in a river flowing at 3 km/h. She rows downstream to a temple and returns to her starting point in 6 hours in all. How far is the temple from her starting point?

A boat goes 30 km upstream and 44 km downstream in 10 hours. It also goes 40 km upstream and 55 km downstream in 13 hours. What is the speed of the boat in still water?
