Question

A SPACECRAFT ORBITING THE EARTH TRAVELS 59 400KM IN 1.5H WHAT IS THE AVERAGE SPEED OF THE SPACECRAFT IN M/S AND KM/H

Answer 1

By definition, the speed of the spacecraft in km/h is:

$$v = \dfrac{59400\space km}{1.5h} = 39600\space km/h$$

In order to convert in m/s one should divide this number by $3.6$. Thus, obtain:

$$v = \dfrac{39600}{3.6} = 11000\space m/s$$

Answer. $39600\space km/h$ and $11000\space m/s$.
