1 light hour = 675000000 miles
Explanation:
The Speed of light is a constant. Light travels at about 300,000 km in one second.
1 hour has 60 minutes and one minute has 60 seconds, so light will travel about 60 * 60 * 300, 000 = 1080000000 km in an hour.
1 mile = 1.6 km
1 km = 1/ 1.6 = 0.625 miles
1080000000 km = 0.625 * 1080000000
1 light hour = 675000000 miles .
