Question

4) During an experiment, a signal from a
spaceship reached the ground station
five minutes. What was the distance of
spaceship from the ground station?
The signal travels at the speed of light
that is 3×10^8 ms^-1​

Answer 1

Let speed = V = 3*10^8 m/s
Let time(t) = 5 minutes = 300 seconds
We know that Distance = Speed/time
Therefore 3*10^8/3*10^2
This is 3*10^6=3000000m=3000km
