During an experiment, a signal from a spaceship from the ground station, the signal travels at the speed of light i.e., 3×108 m s-1.

As we know,

Speed = (i)


Given, Speed = 3×108 ms-1


Distance travelled =?


Time taken = 5 minutes


= 5×60


= 300 seconds


Now we put the values in equation (i), we get


3 × 108 =


Distance travelled = 3×108 × 300


= 9 × 1010 m


Therefore, the distance of spaceship from the ground station is 9 × 1010 metres.
