To find :
Speed = distance / time Distance = 2×3.14×r Distance = 6.28×42,250 Distance = 2,65,330 kilo metres The Circumference or the distance COVERED by the SATELLITE is equal to 2,65,330 kilometres Time taken = 24 hrs Speed = 265330/24 Speed = 11,055.41 km/hr The speed of the satellite is equal to 11,055.41 km/hr |
