Question

A builder wants to buy a pipe that is long enough to cut into four 30-inch pieces , as shown below. Write and solve a division equation that can be used to find the length of the pipe, p, that the builder should buy .

Answer 1

The length of the pipe p, the builder needs to buy is;

`120\text{ inches}`

Step-by-step explanation:

Let p represent the length of the pipe the builder should buy and l represent the length of each of the four piece.

So, we have;

`\begin{gathered} p=4* l \\ p=4l \end{gathered}`

Given in the question;

`l=30\text{inch}`

Substituting we have;

`\begin{gathered} p=4(30) \\ p=120\text{ inches} \end{gathered}`

The length of the pipe p, the builder needs to buy is;

`120\text{ inches}`
