The pipes are 77.5 inches and 19.375 inches.

Explanation:

This question is called a guess and check question. In order to solve it, you have to use the information given and plug numbers into the problem until you get the correct answer.

I came up with 19.375 inches because if you take this value by four, as listed in the problem, it equals the other value, 77.5 inches. Therefore, there are two pipes, one is four times larger than the other, and the combined amount is 155 inches.
