Physics Question?

There are mirrors on the moon on which pulses of light can be transmitted and the time recorded to determine the distance between the moon and the Earth. If a pulse of light is sent to the moon and completes the round-trip in 2.562s, calculate the distance from the Earth to the Moon.

    distance d = c*t/2 = 150,000*2.562 = 384,300 km
