Answer 2

Correct Question

An Athlete completed a 100m race running at a speed of 6.25 m/s . calculate his speed in km/h

Answer

Given : Distance covered in the race by athlete = 100m

Speed of the athlete = 6.25 m/s

To Find

Speed in km/h

Formula used

Speed in km/h = speed in m/s × $\large \sf\frac{60 \times 60}{1000}$

Solution

speed in km/h = 6.25 × $\large \sf\frac{60 \times 60}{1000}$

=22.5 km/h

so, the speed of the athlete in the 100 m race is 22.5 km/h
