A swimmer crosses a flowing stream of width `omega` to and fro in time `t_(1)`. The time taken to cover the same distance up and down the stream is `t_(2)`. If `t_(3)` is the time the swimmer would take to swim a distance `2omega` in still water, then

A

`t_(1)^(2)=t_(2)t_(3)`

B

`t_(2)^(2)=t_(1)t_(3)`

C

`t_(3)^(2)=t_(1)t_(2)`

D

`t_(3)=t_(1)+t_(2)`
