Question

It is estimated that the radio signal takes 1.27 sec to reach the earth from the surface of the moon.Calculate the distance of the moon from the earth.Speed of radio signal is 3*10 power 8( speed of light)

Answer 1

Given :

Time taken(t) = 1.27s  ,speed (v) = 3x108m/s

 We know that  , distance = speed  x time

                                           = 3 x 108  x 1.27

                                              = 3.81 x108

                                            =381000km

Distance between the earth and the moon =381000km
