A boat covers a distance of 36 km upstream of a river in 9 hours. How much time will it take to cover the same distance downstream, if the speed of the current is 1/5 of the speed of the boat in still water?

A speedboat, whose speed in 20 km/h in still water, goes 35 km downstream and comes back in a total of 8 hours. What is the speed of the stream?

A boat that can travel with a speed of 30 km/h in still water takes 2 hours to cover the distance of 48 km while travelling in the opposite direction of the stream. What is the speed of the stream?

A boat goes 60 km upstream in 4 hours and 45 km downstream in 1.5 hours in a river. What is the speed of the boat in still water?

A boat covers 24 km upstream and 36 km downstream in 10 hours and 36 km upstream and 24 km downstream in 12 hours. The speed of the current is:

A boat covers 35 km downstream in 2 h and covers the same distance upstream in 7 h. Find the speed (in km/h) of the boat in still water

Two boats 50 km apart travel towards each other. Speeds of the two boats A and B in still water are 12 km/hr and 13 km/hr respectively. If A goes downstream and B goes upstream. They will meet after what time.
