Question

Mujtaba covered 500m in 30 minutes find the speed in metre per second and km per hour

Answer 1

By definition, the speed is:

$$v = \dfrac{500m}{30min} = \dfrac{50}{3}m/min$$

In meters per second:

$$v = \dfrac{50}{3}\cdot \dfrac{1}{60}m/s \approx 0.28m/s$$

In km/h:

$$v = \dfrac{50}{3}\cdot 0.001\cdot 60 = 1km/h$$
