Calculate the time for light emitted by the Sun to reach the Earth. Express the results in seconds, hours, minutes, and days. The speed of light (c) is 2.99 × 1010 cm/*. Look up the length of one AU in Appendix 1.
Speed = distance/time; time = distance/speed
t = (149.6 x 106 x 1000 x 100)/(2.99 x 1010) = 500.33s
t = 500.33/60 = 8.33min
t = 8.33/60 = 0.138h
t = 0.138/24 = 0.00579d
