best_answer

Given, Radius of the circular orbit = 42250\ km

\therefore Circumference of the orbit = 2\pi r = 2.\frac{22}{7}. (42250) = 265571.4\ km

The satellite takes 24 hours to revolve around the earth.

We know, Speed = \frac{Distance}{Time}

\\ = \frac{265571.4}{24} \\ \\ = 11065.4\ kmh^{-1} \\ \\ = \frac{11065.4}{3600}\ kms^{-1} \\ \\ = 3.07\ kms^{-1}

Therefore, the speed of the artificial satellite is 3.07\ kms^{-1}
