Question

Radio signals travel at a rate of 3 × 108 meters per second. How many seconds will it take for a radio signal to travel from a satellite to the surface of the Earth if the satellite is orbiting at a height of 3.6 × 107 meters?

Answer 1

0.12 seconds

Explanation:

speed = distance / time

so time = distance / speed

time taken = 3.6 * 10^7 / 3 * 10^8

= 1.2 * 10^-1 seconds

= 0.12 seconds answer
