A person rows a boat across a river making an angle of `60^@` with the downstream. Find the percentage time he would have saved, and he crossed the river in the shortest possible time.

A

`13.4`%

B

`25.5`%

C

`12.5`%

D

`20.5` %

Text Solution

Verified by Experts

The correct Answer is:
a
% time saved `=(L)/(V sin 60^(@))/(L)/(V sin 60^(@))=13.4` %
