If a man rows at the rate of 5 kmph in still water and his rate against the current is 3.5 kmph. then the man's rate along the current is
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 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?
1.2 : 1
2.3 : 1
3. 8 : 3
4.Cannot be determined
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?
1.1 : 2
2.3 : 1
3.2 : 1
4. 1 : 3
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:
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?
3.1 hr 15 Min
4.1 Hr 30 Min
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 it take to go 5 km in stationary water?
1. 40 minutes
3.1 hr 15 min
4.1 hr 30 min
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 man can row 9 1/3 km/hr in still water and he finds that is thrice as much time to row u p than as to row down the same distance in river. The speed of the current is:
1.3 1/3 km/hr
2.3 1/9 km/hr
3.1 ¼ km/hr
4.4 2/3 km/hr
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?
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 three-quarters of a kilometre against the stream in 11 minutes and down the stream in 7 minutes. The speed (in km/hr) of the man in still water is:
A man takes twice as long to row a distance against the stream as to row the same distance in favour of the stream. The ratio of the speed of the boat (in still water) and the stream is:
1.2 : 1
2. 3 : 1
3. 3 : 2
4.4 : 3
In a river, a man takes 3 hours in rowing 3 km upstream or 15 km downstream. What is the speed of the current?
Speed of a boat in standing water is 9 kmph and the speed of the stream is 1.5 kmph. A man rows to a place at a distance of 105 km and comes back to the starting point. The total time taken by him is:
The speed of a boat in still water is 2km/hr. If its speed upstream be 1km/hr then speed of the stream is
