Question

hair grows 1/2 inch each month. after you shave your heard, how many years wilt be until your hair is 1 foot in length?

Answer 1

It will take 24 months

Explanation:

1 foot = 12 inches

We need to determine how long it will take to grow 12 inches

The rate is 1/2 inch per month

Length = rate * time

12 inches = 1/2 inch * time

Multiply each side by 2 to isolate time

12*2 = 1/2 *2 * time

24 = time

It will take 24 months
