The distance from the Earth to the sun is approximately 9.37 x 10^7 miles. How long does it take for light from the sun, to reach the earth? Speed of light is 3.00 x 10^8 m/s. Use dimensional analysis to solve.

Answer 1

Convert miles to meters = approx 1.5E11 meters

Then 3E8 m/s x # sec = 1.5E11

Convert to minutes by dividing the answer by 60 sec/min

Answer 2

The distance from the Earth to the sun is approximately 9.37 x 10^7 miles. How long does it take for light from the sun, to reach the earth?
