Question

A signal from a spaceship reached the ground station in 5 minutes what was the distance for the ground station. hint =speed of light =3×10 to the power of 3 metre per second​

Answer 1

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.
