The answer is 0.118 seconds.
The velocity (v) is the distance (d) divided by time (t):
v = d ÷ t
It is given:
v = 3.00 × 10⁸ meters per second
d = 3.54 × 10⁷ meters
It is unknown:
t = ?
If:
v = d ÷ t
Then:
t = d ÷ v
t = 3.54 × 10⁷ meters ÷ 3.00 × 10⁸ meters/second
t = 1.18 × 10⁻¹ seconds
t = 0.118 seconds
Therefore, radio signal will travel from a satellite to the surface ofEarth 0.118 seconds.
