When a boat travels in a river (strictly...

When a boat travels in a river (strictly in a straight line), it can go either in the direction of flow of river (i.e downstream) or in the direction opposite the flow of river (i.e. upstrem ). Thus the boat's actual speed is more than by which it can move in stationary water while travelling downstram (as river's flow speed is added to it) and less while travelling upstream (as the boat moves against the flow of river).Based on the given information answer the following questions A boat going downstream in a following river overcome a raft at a point P. 1 h later it turned back and after some time passed the raft at a distance 6 km from point P.
After reversing its direction ,how much time was taken by the boat to meet the raft again ( i.e. `2^(nd)` time) ?

A

2h

B

1 h

C

30 min

D

3h

A motorboat can travel at 10 km/h in still water. It travelled 91km downstream in a river and then re- turned to the same place, taking altogether 20 h. The rate of flow of river is

A boat takes 4 hrs to travel certain distance in a river in down stream and it takes 6 hrs to travel the same distance in upstream. Then the time taken by the boat to travel the same distance in still water is

The upstream speed of a boat is 9 km/hr which is 300% more than the speed of stream . Find how much distance boat will cover in 5 hours while travelling in downstream .

A boat, which can travel at a speed of 8 km/h in still water on a lake, is rowing in the flowing water in river. If the stream speed is 3 km/h, how fast the boat can cross a tree on the shore in traveling downstream ?
