How many miles does light travel in one hour?
1 light hour = 675000000 miles
Light travels at a constant speed; it covers a distance of roughly 300,000 km in a second.
Since there are 60 minutes in an hour and 60 seconds in a minute, light travels 60 * 60 * 300,000 = 1080000000 km in an hour.
One mile is equivalent to 1.6 kilometers.
0.625 miles per km = 1/1.6
0.625 * 1080000000 km = 1080000000 km
675000000 miles in one light hour.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
