A swimmer's speed in the direction of flow of river is `16 km h^(- 1)` . Against the direction of flow of river, the swimmer's speed is 8 km `h^(-1)` . The swimmer's speed in still water and the velocity of flow of the river respectively are

A

`12km h^(-1) , 4km h^(-1)`

B

`4km h^(-1), 12 km h^(-1)`

C

`24 km h^(-1) , 16 kmh^(-1)`

D

`16km h^(-1) , 24 km h^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
According to the question u + v = 16 and u - v = 8
By solving, we get the speed of swimmer in still water, u ` = 12km h^(-1)`
Speed of flow of river ` v = 4kmh^(-1)`
