A man wishes to cross a river of width 120 m by a motorboat. His rowing speed in still water is 3 m//s and his maximum walking speed is 1m//s . The river flows with velocity of 4 m//s . (a) Find the path which he should take to get to the point directly opposite to his starting point in the shortest time. (b) Also, find the time which he takes to reach his destination.

A motor boat is to reach at a point 30^@ upstream on other side of the river flowing with velocity 5m//s The velocity of motor boat with respect to water is 5sqrt3 m//s . At what angle the driver should steer the boat ?

Velocity of boat in still water is 13 m/s. If water flows ina river with a velocity of 5 m/s. What is the difference in times taken by him to cross the river in the shortest path and in the shortest time. If the width of the river is 10 m.
