Question

a car travels 50 km in 5 secs find it's speed in m/s and km/h​

Answer 1

50km/5s

Simplified -> 10km/s

1 km = 1000m

∴ 10 km = 10000m

So the car's speed in m/s = 10,000 m/s

1hr = 3600 seconds

∴  $\frac{10}{s}$×$\frac{3600}{3600}$ = $\frac{36000}{3600s}$

= $\frac{36000}{hour}$

= 36,000km/h
