If a man rows at the rate of 5 km/hr in still water and his rate against the current is 3.5 km/hr, then the man's rate along the current is?
Correct Answer: 6.5 km/hr
Explanation:
Speed of current = 5 - 3.5 = 1.5 km/hr
Man's speed along the current = Man speed in still water + speed of current.
⇒ Man's speed along the current = 5 + 1.5 = 6.5 km/hr
