A man's speed with the current is 18 km/hr and the speed of the current is 2.5 km/hr.
A man's speed with the current is 18 km/hr and the speed of the current is 2.5 km/hr. The man's speed against the current is?
Answer/Solution
18
Steps/Work
Man's speed with the current = 18 km/hr
=> speed of the man + speed of the current = 18 km/hr
speed of the current is 2.5 km/hr
Hence, speed of the man = 18 - 2.5 = 20.5 km/hr
man's speed against the current = speed of the man - speed of the current
= 20.5 - 2.5 = 18 km/hr
Answer is B.
=> speed of the man + speed of the current = 18 km/hr
speed of the current is 2.5 km/hr
Hence, speed of the man = 18 - 2.5 = 20.5 km/hr
man's speed against the current = speed of the man - speed of the current
= 20.5 - 2.5 = 18 km/hr
Answer is B.
