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
