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 m/s.
The signal travels in a straight line, the distance between the spaceship and the ground station is equal to the total distance travelled by the signal. 5 minutes = 5*60 seconds = 300 seconds. Speed of the signal = 3 × 108 m/s. = 9*1010 meters.
