A light-year is the distance that light travels in one year. Find the number of miles in a light-year if light travels 1.86 times 10 Superscript 5 miles per second.

Number of miles traveled by light in a light-year is 5.952 * 10^12 miles

Step-by-step explanation:

Step 1: Find the number of miles (distance) in a light year by using the formula for speed = Distance/Time

⇒ Distance = Speed * Time

= 1.86 * 10^5 * 1 yr (convert to seconds)

= 1.86 * 10^5 * 365 days * 24 hrs * 60 mins * 60 sec

= 1.86 * 10^5 * 31,536 * 10³

= 1.86 * 3.2 * 10^5 * 10^7

= 5.952 * 10^12 miles
