To find the number of miles light travels in a year, we need to multiply the speed of light by the number of seconds in a year.
0.2 x 10^5 mi./sec. * 3.2 × 10^7 seconds = 0.2 x 3.2 x 10^5 x 10^7 mi
= 6.4 x 10^5 x 10^7 mi
= 64 x 10^7 mi
= 6.4 x 10^8 mi.
Therefore, light travels approximately 6.4 x 10^8 miles in a year.

Apologies for the mistake. Let's correct the calculation.
The speed of light is approximately 1.9 × 10^5 mi/sec, and there are about 3.2 × 10^7 seconds in a year. To find the total distance light travels in a year, we multiply these two quantities:
1.9 × 10^5 mi/sec * 3.2 × 10^7 seconds = 6.08 × 10^12 mi.
Hence, light travels approximately 6.08 × 10^12 miles in a year.
