A man crosses a river in a boat. If he crosses the river in minimum time he takes 10 min with a drift 120 m . If he crosses the river taking the shortest path, he takes 12.5 min. what is the width of the river ?

A boat has to cross a river. It crosses the river by making an angle of 60^(@) with the bank of the river due to the stream of the river and travels a distance of 600m to reach the another side of the river. What is the width of the river?

A boatsman can travel by his boat a distance of 30 kilometres in 6 hours in favour of the current . While he comes back in 10 hours against the current . Find the velocity of the current and the velocity of the boat in still water.

Velocity of a boat in still water is 5km*h^(-1) . It takes 15 min to cross a river along the width. The river is 1km wide. Find the velocity of current.

The width of a river is D. A man can cross the river in time t_1 in the absence of any river current. But in presence of a certain river current, the man takes a time t_2 to cross the river directly. Show that the velocity of the current is v=D sqrt((1)/(t_1^2)-(1)/(t_2^2))

Two boats, each with velocity 8km*h^(-1) , attempt to cross a river of width 800 m. The velocity of river current is 5 km*h^(-1) . One of the boats crosses the river following the shortest path and the other follows the route in which the time taken is minimum. If they start simultaneously, what would be the time difference between their arrivals at the other bank ?
