The speed of a boat is that of the current of water is 40:3. The boat goes along with the current in 3 hours 8 minutes. It will come back in
A boat travelled 8km upstream in 30 minutes and 6 km downstream in 15 minutes. Then in how long it will take to go 12 km in still water?
Speed of boat is 10 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 90 km downstream?
The speed of the boat in still water is 40% less than the speed of the boat in downstream. The time taken by the boat to cover 468 km distance in upstre...
A motorboat covers a certain distance downstream in a river in 3 hours. It covers the same distance upstream in 3 and a half an hour. If the speed of th...
A man can row at 6 kmph in still water. If the velocity of current is 4 kmph and it takes him 6 hour to row to a place and come back, how far is the place?
A man can row 25/2 km an hour in still water and he finds that it takes him thrice as long as long to row down the river. The rate of stream is:
The speed of the boat in still water is 12 km/hr and the speed of the stream is 9 km/hr. A boat goes 84 km downstream with its usual speed but at the ti...
If the sum of upstream and downstream speed is 30 km/hr and the speed of the current is 6 km/hr. Then find time taken to cover 84 km in downward?
