Boats & Streams Mock Tests

A boat goes 18 km upstream in 3 hours and 36 km downstream in 2 hours. What is the speed of the boat in still water?

A boat goes 12 km/hr in still water and the stream flows at 3 km/hr. The time taken to go 45 km downstream is:

A boat goes 16 km/hr in still water and the speed of the stream is 4 km/hr. The time taken by the boat to go 80 km downstream is:

A man can row downstream at 18 km/hr and upstream at 12 km/hr. What is his speed in still water?

A boat covers a certain distance downstream in 2 hours and returns the same distance in 3 hours. If the speed of the stream is 3 km/hr, find the speed of the boat in still water.

A boat goes 24 km upstream in 4 hours and 36 km downstream in 3 hours. The speed of the boat in still water (in km/hr) is:

A boat goes 15 km downstream in 3 hours and upstream in 5 hours. The speed of the boat in still water is:

A man can row upstream at 8 km/hr and downstream at 12 km/hr. What is the speed of the man in still water?
