A) $80 \times 10 ^ { 12 } \mathrm {~m}$
B) $20 \times 1015 \mathrm {~m}$
C) $95 \times 10 ^ { 14 } \mathrm {~m}$
D) $30 \times 10 ^ { 8 } \mathrm {~m}$
E) $36 \times 10 ^ { 16 } \mathrm {~m}$

The distance light travels in one year, known as a light-year, is calculated by multiplying the speed of light (3.0 x 10^8 m/s) by the number of seconds in a year (365 days x 24 hours/day x 3600 seconds/hour). This calculation gives approximately 9.46 x 10^15 meters, which is closest to the option $95 \times 10 ^ { 14 } \mathrm {~m}$.

How Far Does a Beam of Light Travel Through Space (c=3.0×108 m/s)\left( c = 3.0 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } \right)(c=3.0×108 m/s)
