Answer 2

Answer:

11055.4 km/hr (approx)

Explanation:

Radius=42250 km

Therefore, distance to be travelled is basically circumference of the orbit( as it is revolving in circular motion)

Distance= 2πr= 2×3.14×42250

= 314×845 km.

Speed= dis/time

Time= 24 hours.

Speed= (314×845)/24

= 11055.4 km/hr
