A man is crossing a river flowing with velocity of `5m//s`. He reaches a point directly across at a distance of `60m` in `5sec.` his velocity in still water should be

A

13 m/s

B

14 m/s

C

15 m/s

D

16 m/s

Text Solution

Verified by Experts

The correct Answer is:
a

Component of velocity along AB = `60//5 = 12 m//s` Component of velocity perpendicular to AB = 5 m/s (Since drift is zero) Velocity of man in still water `=sqrt(12^(2)+5^(2))=13 m/s`
