miles
To calculate the number of miles light travels in a year, we can multiply the speed of light by the number of seconds in a year.
Approximate rate of light: 1.9×10^5 mi./sec
Number of seconds in a year: 3.2×10^7 sec
Multiplying these values gives us:
(1.9×10^5 mi./sec) * (3.2×10^7 sec) = 6.08×10^12 mi.
Therefore, light travels approximately 6.08×10^12 miles in a year.
