A man swim at an angle `theta=120^(@)` to the direction of water flow with a speed `V_(mw)`=5 km/hr relative to water.If the speed of water `V_(w)`=3 km/hr, Find the speed of the man.

A man crosses the river in shortest time and reaches at an angle theta= 60^(@) to the direction of flow of water. If the speed of water is v_w = 4 km//hr , find the speed of the man:

A man can walk on the shore at a speed v_1 = 6 km/hr & swim in still water with a speed V_2 = 5 km/hr. If the speed of water is V_3 = 4 km/hr, at what angle should he head in the river in order to reach the exactly opposite point of the other shore in "shortest time including his swimming & walking?

A man can swim at a speed 2ms^(-1) in still water. He starts swimming in a river at an angle 150^(@) with direction of flow of water and reaches at the exactly oppsite point on the opposite bank. (a) Find the speed of flowing water. (b) If width of river is 1 km then calculate the time taken also
