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
upstream ?

Text Solution

Verified by Experts

In this case the stream is carrying the boat in the same direction in which the boat is trying to move. Hence its speed with respect to the tree is 8 + 3 = 11 km/h.
