Answer:The speed of light can be used with time of flight measurements to measure large distances to high precision. Ole Rømer first demonstrated in 1676 that light travels at a finite speed (as opposed to instantaneously) by studying the apparent motion of Jupiter's moon Io.
Explanation:One light year: 1.0 year
Distance: Time
Metres per second: 299792458
From Moon to Earth: 1.3 s
