A light year is the distance that light travels in one year. Find the number of miles in a light-year if light travels 1.8x10^5 mi per sec.

5.67648 * 10^12 miles

Step-by-step explanation:

Given that:

Speed of light = 1.8x10^5 mi per sec.

The number of miles in a light year will be :

Distance = speed * time

The time in seconds in a year is :

365 days * 24 hours * 60 mins * 60 sec = 31536000 seconds

Hence,

The number of miles in a light year :

1.8x10^5 * 31536000 = 5676480000000

= 5.67648 * 10^12 miles
