How many times longer does it take light from the Sun to reach Neptune than Mercury? Express this number in standard notation. E
stealth61 [152]

9514 1404 393

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.
