Question

3. A postal carrier can

deliver to 130 houses in 2.5
hour period. At this rate, how
many hours will it take to
deliver to 312 houses?

Answer 1

It will take the driver 15 hours to deliver to 312 houses.

Explanation:

Divide 2.5 by 130, you will get 52.Next add 52 by 52, you will get 104. Then multiply 104 by 3, you will get 312. After multiply 3 by 2, you will get 6. Last multiply 2.5 by 6, and you will have your answer.

2.5 ÷ 130 = 52

52 + 52 = 104

104 x 3 = 312

3 x 2 = 6

2.5 x 6 = 15

I Hope This Helps!

Answer 2

6 hours. ( I DID IT USING PROPORTIONS!)

Explanation:

houses/hours

130/2.5= 312/x

(cross multiply)

130x = 780

130x/130 = 780/ 130 (divide each by 130)

6 = h
