A boat man could row his boat with a speed 10 m/sec. He wants to take his boat from P to a point Q just opposite on the other bank of the river flowing at a speed 4 m/sec. He should row his boat–

A river of width 80m is flowing at 6 m/s. A motorboat crosses the river in 10s and reaches a point directly across on the other river bank. The velocity of motorboat in still water is :

A river flows at the rate of 3km/hr and a person can row a boat at a speed of 5km/hr in still water.If the difference between the times taken to cross the river by the shortest path and the quickest path be 4 minutes,the width of the river is (in km)

A river is flowing from north to south at a speed of 0.3 kph. A man on the west bank of the river, capable of swimming 1 kph in still water, wants to swim across the river in the shortest time. He should in a direction:

Tilak rowed through the river and tied his boat on the other side.

A river flows with a speed more than the maximum speed with which a person can swim in still water. He intends to cross the river by the shortest possible path (i.e., he wants to reach the point on the opposite bank which directly opposite to the starting point). Which of the following is correct ?

A river is flowing towards with a velocity of 5 m s^-1 . The boat velocity is 10 ms^-1 . The boat crosses the river by shortest path. Hence,

A man can swim with a speed v relative to water . There is a river of width d which is flowing at a speed u . A is the point on river bank from where he starts and B is point directly opposite to A on the other side of the river .
