the earth is 93 million miles from the sun. how long in seconds does it takes light from the sun to reach earth? use the speed of light to be 1.86 times 10 to the negative 5 miles per hour
Since the distance is 93,000,000 miles, and light travels 186,282 miles per second, we have:
93,000,000/186,282=499.24seconds for light to travel from Sun to Earth. Or 499.24/60=8 minutes and 19 1/4 seconds
That SHOULD read 1.86 x 10 to the POSITIVE 5 miles PER SECOND.
