Question

Light from the sun travels to Earth at a speed of 1.86 × 105 miles/second. How much time will the light take to cover a distance of 9.2 × 107 miles? Write your answer in scientific notation, and round so the first factor goes to the hundredths place.

Answer 1

4.95x10^2

9.2/1.86=4.95
10^7/10^5=10^2
