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.

Answer

Here we have, speed = 3×10⁸ m/s

Time = 5 minute = 5 × 60 s = 300 s

Using, Distance = Speed × Time

⇒ Distance = 3 ×10⁸ × 300 m = 900 × 10⁸ m= 9.0 × 10¹⁰ m
