In the city of Erie, 8 meters of snow fell in 20 days. At this rate, how much snow would fall in 60 days?

Question

(a) Let A be the unknown amount of snow that would fall (in meters). Using the values below, create a proportion that can be used to find A.
Values: _?_/_?_ _?_/_?_

(b) Use the proportion from part (a) to find the amount of snow that would fall in 60 days. Do not round any computations.

___meters

Answer 1

(a) The proportion can be set up as follows:

8 meters / 20 days = A meters / 60 days

(b) To solve for A, cross multiply:

20A = 8 * 60

Divide both sides by 20:

A = (8 * 60) / 20

A = 24 * 3

A = 72 meters

Therefore, 72 meters of snow would fall in 60 days.
