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

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
