Answer 2

Answer:

Man's rate in still water =(15−2.5)km/hr=12.5km/hr.

Man's rate against the current =(12.5−2.5)km/hr=10km/hr.

Explanation:

let the speed of man is = x km/h speed of current = 2.5 km/h when the speed of man with current =15km/h then without current 15-2.5 =12.5km/h now the speed of man against the current is = 12.5 - 2.5 =10km/h.
