Hlo mate here is ur ans...

Distance covered by the satellite in 24 hours

Distance covered by the satellite in 24 hourss=2πr

=2×3.14×42250=265464.58 km

=2×3.14×42250=265464.58 kmTherefore speed of satellite,

=2×3.14×42250=265464.58 kmTherefore speed of satellite,v= time taken distance travelled

distance travelled

distance travelled = 24×60×60

distance travelled = 24×60×60265464.58

distance travelled = 24×60×60265464.58

distance travelled = 24×60×60265464.58 =3.07 km s^−1

−1
