Question

Light travels at a speed of about 186,000 miles per second. How far does light travel in 5 second? Use repeated addition to solve.

Answer 1

Explanation:

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometres per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.

186 ,282 x 5 = 931 , 410 for 5 seconds
