Question

A man can row upstream at 16 km/hr and downstream at 24 km/hr. Find the speed of the current.
A) 4 kmph
B) 6 kmph
C) 5 kmph
D) 3 kmph

Answer 1

Please remember,
If a is rate downstream and b is rate upstream 
Rate in still water = 1/2(a+b)
Rate of current = 1/2(a-b)

=> Rate in still water = 1/2(20+10) = 15 kmph
=> Rate of current = 1/2(20-10) = 5 kmph
