A swimmer swims from a point A against a current for 5 min and then swims backwards in favour of the current for next 5 min and comes to the point B. If AB = 100 m, then the speed of the current in (km/h) is

B.
0.6
Let the speed of boat be x km/hr and speed of current be y km/hr
OA = Distance covered by upstream speed in 5 minutes
OB = Distance covered by downstream speed in 5 minutes
According to the question,
OB - OA = AB
∴ Speed of the current = 0.6 km/hr.
