Answer:

v = 11061.02 km/h

Explanation:

Given that,

The radius of the circular orbit, r = 42250 km

Time taken to revolve around the Earth, t = 24 hours

We need to find the speed of the satellite. We know that, speed of an object is equal to total distance traveled divided by the time taken. So,

v=\dfrac{2\pi r}{T}

Put all the values,

v=\dfrac{2\pi \times 42250}{24}\\\\v=11061.02\ km/h

So, the speed of the satellite is equal to 11061.02 km/h.
