362093 In a river of width 200 \(m\), flow speed is 10 \(m\)/\(s\). A swimmer wants to cross the river along the shortest path and starts swimming with a speed of 20 \(m\)/\(s\). Angle between his velocity and velocity of flow is

362094 A man wishes to cross a river in a boat. If he crosses the river in minimum time he takes 10 minutes with a drift of 120 \(m\). If he crosses the river taking shortest route, he takes 12.5 minutes. Find velocity of the boat with respect to water.

362095 A swimmer can swim in still water with a speed of 4 \(m\)/\(s\). While crossing a river his average speed is 5 \(m\)/\(s\). If he cross the river in the shortest possible time, what is the speed of flow of water?
