Question

A message is sent from the Galileo spacecraft orbiting Jupiter to earth at a distance of 928,000,000km. If it took the signal 51.6 minutes to arrive, what is the calculated the speed of the signal in km/s?

Answer 1

The answer would approximately be 299,741.60

Answer 2

speed of signal = 299742 km/s

Explanation:

$V=\frac{d}{t}$

d= distance=928,000,000 km

t= time=51.6 min= 51.6 (60)= 3096 s

so v= 928,000,000/3096

v=299742 km/s
