Arithmetic Aptitude :: Boats and Streams
- A man can row at 5 km/hr in still water, if the river is running at 1 km/hr it takes him 75 minutes to row to a place and back. How far is the place?
- In a river, a man takes 3 hours in rowing 3 km upstream or 15 km downstream. What is the speed of the current?
- A boat running upstream takes 8 hours 48 min to cover a certain distance while it takes 4 hours to cover the same distance running downstream. What is the ratio between the speed of the boat and the speed of water current respectively?
- A boat goes 6 km in an hour in still water. It takes thrice as much time in covering the same distance against the current. Speed of the current is?
- A man can row three-quarters of a kilometer against the stream in 11 ¼ minutes and return in 7 ½ minutes. The speed of the man in still water is?
- A man can row 7 ½ kms on hour in still water and he finds that it takes hi twice as long to row down the river. The rate of stream is
- A boatman goes 2 km against the current of the stream in 1 hour and goes 1 km along the current in 10 minutes. How long will he take to go 5km in stationery water?
- A boat takes half time in moving a certain distance downstream than upstream. What is the ratio between the rate in still water and rate of current?
- The speed of a boat in still water is 2km/hr. If its speed upstream be 1km/hr then speed of the stream is
- A boat travels upstream from B to A and downstream from A to B in 3 hours. If the speed of the boat in still water is 9km/hr and the speed of the current is 3km/hr, the distance A and B is:
