Physics repost please clarify

The distance between earth and the moon can be determined from the time it takes for a laser beam to travel from earth to a reflector on the moon and back. If the round-trip time can be measured to an accuracy of 0.19 of a nanosecond (1 ns = 10-9 s), what is the corresponding error in the earth-moon distance?

  • Physics repost please clarify -

    How far does light travel in .19ns?

    distanceerror=c*deltatime
    that will give you the distance error

    I think I am missing it. How do I get the change in time.

  • Physics repost please clarify -

    change in time is given. That time is infact the time error.
