Question
A man is crossing a river which is flowing with velocity of 5m / s. He reaches a point directly across at distance of 60 m in 5s. His velocity in still water should be : -
Options
A.12 m/s.
B.13 m/s
C.5 m/s
D.10 m/s
Solution
The resultant velocity should be in the direction of resultant displacement
So time =
= 5
∵ vm = 13 m/s
So time =
= 5∵ vm = 13 m/s
