Answer to Question #291829 in Optics for Mark

Question

a global positioning system (GPS) receives a radio signal from a satrlite in 1.7 x 10-⁴ seconds. Assuming vacuum conditions for simplicity, how far is the the GPS receiver from the satellite?

Answer 1

Know we know that

$t=1.7\times10^{-4}s$

$R=3\times10^8m/sec$

Now

$D=R\times t$

Put value

$$D=3\times10^{8}\times1.7\times10^{-4}=51\times10^3m$$
