A man who can swim at a speed v relative to the water wants to cross a river of width d, flowing with a speed u. The point opposite him across the river is P.

A

The minimum time in which he can cross the river is `(d)/(v)`

B

He can reach the point P in time `(d)/(v)`

C

He can reach the point P in time `(d)/(sqrt(v^(2)-u^(2))`

D

He cannot reach P if `u gt v`
