*How many times could light travel around the circumference of the Earth in 8.6 second? Let the circumference of the Earth be 24,000 miles.*

Light travels at 186,000 miles per second

Divide 186,000 by 24,000 and the quotient is 7**.**75

That's how many times light would go around the world in 1 second

Multiply 7**.**75 by 8**.**6 and the product is 66**.**65

That's how many times light would go around the world in 8**.**6 seconds **66.65 times**
