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

Answer 2

We have that the time for light to cover a distance  is mathematically given as

T=6.924ses

Time  to cover a distance

Question Parameters:

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

Generally the equation for the Time  is mathematically given as

$T=\frac{d}{v}$

Therefore

$T=\frac{9.2e7}{1.86e5}$

T=6.924ses
