A river is flowing at `3m//s` . A boat can move at `5m//s` in still water. Boat starts from point `A`. Width of river is `120m`. Select the incorrect statement `:-`
.

A 400 m wide river is flowing from west to east at velocity 3m/s. A boat starts from one bank and it crosses the river along the shortest path. When it reaches the middle of river, wind starts blowing horizontally along north-east at a velocity sqrt(2) m/s . Due to this, the direction of rowing of boat has to be changed for the boat to move along the shortest path. If the velocity of boat in still water with no wind blowing is 5 m/s, then choose the correct option(s).

Velocity of the river water is 3m/s and velocity of a boat in still waters is 5m/s. If the distance between the banks of a river is 50 m, then calculate the time taken for (i) shortest distance to cover

Velocity of the river water is 3m/s and velocity of a boat in still waters in 5m/s. If the distance between the banks of a river is 50 m, then calculate the time taken for (ii) longest distance to cover.

The river flows at 4 km/h. A boat can go downstream thrice as fast as upstream The speed of boat in still water is

A river is flowing due east with a speed 3m//s . A wimmer can swim in still water at a speed of 4 m//s . If swimmer starts swimming due north, what will be his resultant velocity (magnitude and direction) ?

A river 500m wide is flowing at a rate of 4 m//s. A boat is sailing at a velocity of 10 m//s with respect to the water, in a direction perpendicular to the river. The time taken by the boat to reach the opposite bank

A river 500m wide is flowing at a rate of 4 m//s. A boat is sailing at a velocity of 10 m//s with respect to the water, in a direction perpendicular to the river. The time taken by the boat to reach the opposite bank

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 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 man with some passengers in his boat, starts perpendicular to flow of river 200 m wide and flowing with 2 m//s. Speed of boat in still water is 4 m//s. When he reaches half the width of river the passengers asked him that they want to reach the just opposite end from where they have started. (a) Find the direction due which he must row to reach the required end. (b) How many times more time, it would take to that if he would have denied the passengers?
