A person can swim in still water at the rate of 1km/hr. He tries to cross river by swimming perpendicular to the river flowing at the rate of 2km/hr. if the width of the river is 10m find the location of the point where he lands on the other side of the river , also find time taken by him to cross the river. (Answer Fast)
Width of the river = 10 m = 0.01 km
Velocity of the river = 2 km/h
Velocity of the man = 1 km/h
Location of the point other side the river , x = 0.01 × 2 / 1 = 0.02 km = 20 m
Time taken to cross the river ,
Velocity of the river = 2 km/h
Velocity of the man = 1 km/h
Location of the point other side the river , x = 0.01 × 2 / 1 = 0.02 km = 20 m
Time taken to cross the river ,
