In this problem we are given with the speed of the signal and the distance travelled and is asked to determine the time of travel. IN this case, the expression that can be applied is
time = distance / speed
= (3.6 × 10⁷ m) / (3 × 10⁸ m/s)
= (3.6 / 3) × 10⁷⁻⁸ s
= 1.2 × 10⁻¹ s
t= 0.12 s
time = distance / speed
= (3.6 × 10⁷ m) / (3 × 10⁸ m/s)
= (3.6 / 3) × 10⁷⁻⁸ s
= 1.2 × 10⁻¹ s
t= 0.12 s
