Question

A swimmer is capable of swimming at a speed of 1.4 m/s in still water. What is the speed of the swimmer in km/h?

1) 5.04 km/h
2) 3.36 km/h
3) 8.96 km/h
4) 2.8 km/h

Answer 1

The speed of the swimmer in still water is 1.4 m/s, which is equal to 5.04 km/h.

Step-by-step explanation:

The speed of the swimmer in still water is 1.4 m/s. To convert this to km/h, we need to multiply by a conversion factor. 1 m/s is equal to 3.6 km/h, so the speed of the swimmer in km/h is 1.4 m/s x 3.6 km/h = 5.04 km/h. Therefore, the correct answer is option 1) 5.04 km/h.
