Explanation:
Detailed explanation-1: -How many miles does light travel in 1 hour? The speed of light is 1.86times10^5 miles per second.
Detailed explanation-2: -What about light hours? How fast can light travel in an hour? To calculate how fast light can travel in an hour multiply the distance light can travel in a minute by 60 since there is 60 minutes in an hour. So light travels 1, 080, 000, 000 kilometers or 669, 600, 000 miles in one hour!
Detailed explanation-3: -Light is fast! It can reach the universal speed limit-186, 000 miles per second. (If you could travel as fast as light, the universe would look very different.) Because it moves so quickly, light can seem to appear instantaneously.
