That works out to 2.17 inches per minute, which sounds like a fast land-snail or slug. Strange.
light travels 5,878,630,000,000 miles in a year.
Earth travels approximately 584 million miles in its orbit around the Sun every year.
One light year (the distance light travels in one year) is:5,878,625,373,000,000,000,000 miles.
(18 miles) / (20 minutes) = (18 miles) / (1/3rd hour) = (3 x 18) mi/hr = 54 miles per hour.
The time of 20 mins is multiplied by 3 to get to the 'per hour" so car travels 18 miles times 3 = 54 miles per hour the answer is 54 mph
14 hours (252/18 = 14).
It gets it name because it is the distance that light travels in one Earth year.
