Radio signals travel at a rate of 3 x 10^8 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 7.5 x 10^6 meters?
2 answers:
The answer would be 0.025 seconds.
3x10^8=300,000,000mps
7.5x10^6=7,500,000m
do 7,500,000/300,000,00 and that equals 0.025secs
