Question

A man’s speed with the current is 15 km/hr and the speed of the current is 2.5 km/hr. The man’s speed against the current is

Answer 1

Man's speed with the current = 15 km/hr
=> speed of the man + speed of the current = 15 km/hr

Speed of the current is 2.5 km/hr

Hence, speed of the man = 15 - 2.5 = 12.5 km/hr

Man's speed against the current = speed of the man - speed of the current
= 12.5 - 2.5 = 10 km/hr
