Light travels approximately 982,080,000 ft/s, and one year has approximately 32,000,000 seconds. A light year is the distance light travels in one year. State the speed in mi/s, using scientific notation. (1 mile = 5280 feet exactly, by definition; i.e., this is not a measurement.) A. 1.8600 x 105 mi/s Light travels approximately 982,080,000 ft/s, and one year has approximately 32,000,000 seconds. A light year is the distance light travels in one year.

A. 1.8600 x 105 mi/s

Explanation:

The problem gives us the value of the speed of light in ft/s: [tex]v=982,080,000 ft/s[/tex]

We know the conversion factor between feet and miles:

[tex]1 mi = 5280 ft[/tex]

So we can apply this conversion factor to the speed of light:

[tex]v=982,080,000 ft/s \cdot \frac{1}{5280 ft/mi}=186,000 mi/s=1.86\cdot 10^5 mi/s[/tex]
