Answer:
77.6
Step-by-step explanation:
The ratio of light times will be the ratio of distances:
(light time to Neptune) / (light time to Mercury)
= (Neptune distance)/(Mercury distance)
= (27.93×10^8 mi)/(0.3598×10^8 mi) = 27.93/0.3598
≈ 77.6
It takes about 77.6 times as long for light to reach Neptune as it does to reach Mercury.
