A bank on an excavation site has a 3 to 1 slope; how many inches per foot will the bank rise?

Explanation:
A 3 to 1 slope in this context means three units of horizontal distance for every one unit of vertical rise. So for each 1 foot (12 inches) of horizontal run, the vertical rise is 12 inches divided by 3, which equals 4 inches. In other words, the bank rises 4 inches for every foot of horizontal distance. (For 3 feet of horizontal, the rise would be 1 foot, i.e., 12 inches.)
