Question

A radio signal from a gps satellite take only about 0.067 seconds to reach a GPS reciever. If the speed of light is about 300,000km/s, then approximately how far away is the reciever from from the satellite?

Answer 1

Answer: The receiver from the satellite is 20,100 km far away.

Explanation:

Time taken by the signal to reach the GPS = 0.067 seconds

Speed of the signal = 300,000 km/s

Distance of receiver from the satellite= D

$Speed=\frac{Distance}{Time}$

$Distance=Speed\times Time=300,000 km/s\times 0.067 s=20,100 km$

The receiver from the satellite is 20,100 km far away.
