A man swims across a river with speed of...

A man swims across a river with speed of ` 5 km h^(-1)` ( in still water). While a boat goes upstream with speed ` 12 km h^(-1)` ( in still water). How fast and in which direction does, the man appear to go to the boatman ? Given that the speed of flowing water is ` 2 km h^(-1)`

A

`13 kmh ^(-1) ` in a direction making angle ` tan^(-1) ((5)/(12))` with x-axis

B

`13 kmh^(-1)` in a direction making angle ` tan^(-1) ((5)/(12))` with y-axis

C

`13 kmh^(-1) ` in a direction making angle `tan^(-1) ((3)/(4))` with x-axis

D

` 13 kmh^(-1)` in a direction making angle ` tan^(-1) ((3)/(4))` with y-axis
