Question

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. What is the answer?

Answer 1

This is the answer for the question
We have,
speed of light(s)=3*10^8 m/s
Time taken(t)=5 min =300 s
Distance(d)=s*t
                 =3*10^8*300
                  =9^10 m is the distance between spaceship and ground station.

Answer 2

Speed= 3 × 108 m s-1

Time= 5 min = 5 *60 = 300 seconds.

Distance= Speed * Time

Distance= 3 * 108 m s-1 * 300 secs. = 9 x 1010m
