Question

What is the speed in miles per second of a beam of light traveling at 3.00×108m/s?

Answer 1

• 186411.82 miles per second

--------------------

Use the conversion factor:

• 1 mile = 1609.34 meters

Divide the speed in m/s by the number of meters in a mile:

• (3.00 × 10⁸) / 1609.34 = 186411.82
