A swimmer can swim downstream at 37 km/hr and upstream at 27 km/hr. What is the speed of the swimmer in still water?

Correct option is C

Given:

Downstream speed = 37 km/h

Upstream speed = 27 km/h

Formula Used:

Speed in still water = $$\frac{\text{Downstream speed} + \text{Upstream speed}}{2}$$​​

Solution:

Speed in still water = $$\frac{37 + 27}{2} = \frac{64}{2} = 32 \text{ km/h}$$​​
