For a 40-foot run of pipe with a pitch of 1/8 inch per foot, what is the total amount of pitch over the entire run?

To determine the total amount of pitch over a 40-foot run of pipe at a pitch of 1/8 inch per foot, you need to first calculate the pitch per foot and then multiply it by the total number of feet in the run.

The pitch is specified as 1/8 inch for every foot. Therefore, over a 40-foot length, the total pitch would be calculated as follows:

1. First, convert the pitch per foot into a common measurement:

• 1/8 inch is equivalent to 0.125 inches.

2. Multiply the pitch per foot by the total length of the pipe:

• 0.125 inches/foot × 40 feet = 5 inches.

This means that for the entire run of 40 feet, the total amount of pitch will be 5 inches. Thus, the correct answer is 5 inches.

Other options do not accurately reflect this multiplication and result in incorrect total amounts. It's crucial while working on such problems to carefully perform the necessary calculations to arrive at the correct total pitch, emphasizing the relationship between the units of measurement and the total distance.
