During an experiment, a signal from a spaceship reached the ground station in five minutes. What was the distance of the spaceship from the ground station? The signal travels at the speed of light, that is, 3 × 108 ms–1.
Distance = time × speed
Time = 5 minutes × 60 = 300 seconds
Speed = 3 × 108 m/s
Distance = 300 × 3 × 108
= 9 × 1010 m
= 9 × 107 km
