To find the distance in miles, first calculate the distance light travels in meters in one year: (3.00 × 10^8 m/s) × (60 s/min) × (60 min/hr) × (24 hr/day) × (365.25 days/year). Convert meters to kilometers (1 km = 1000 m), then convert kilometers to miles (1 mi = 1.609 km). The result is approximately 5.88 × 10^12 miles.
