[" A boat can move in still water with "5km/h," in "1km" wide river.A boat cross the 1"],[" path in "15min." Find velocity of river in "km/hr" ? "]

A boat which has a speed of 5 km/hr in still water crosses a river of width 1 km along the shortest possible path in 15 minutes. The velocity of the river water in km/hr is

The speed of a boat is 5 km/h in still-water. It crosses a river of width 1 km along the shortest path in 20 min. The velocity of river water in km/h is

The speed of boat is 5 kmh^(-1) in still water. It crosses a river of width 1 km along the shortest possible path in 15 min. Then, velocity of river will be

A boat which has a speed of 6km/h in still water crosses a river of width 1 km along the shortest possible path in 20 min. the velocity of the river water in km/h is

A boat which has a speed of 6km/h in still water crosses a river of width 1 km along the shortest possible path in 20 min. the velocity of the river water in km/h is
