Question

5. 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 x 10⁸ m s^-1.​

Answer 1

Answer:

The distance between the spaceship and ground station is 9 × 10¹⁰

Explanation:

Speed of light = 3 × 10⁸ m/s

Time taken to reach ground station = 5 min = 300 seconds

Therefore,

Distance = Speed × Time

=> D = 3 × 10⁸ × 300

=> D = 9 × 10¹⁰ meters.

Answer 2

Explanation:

speed = distance/ time

distance = speed× time

d = 3×10^8 ×5×60

= 900× 10^8

= 9×10^10
