Question

Bob had three 10' lengths of conduit. If he used a total of 13.75' of conduit to install a motor, how much total conduit does he have left?

Answer 1

Given that Bob had three 10' lengths of conduit and he used a total of 13.75' of conduit to install a motor.

To find how much total conduit he has left we would subtract the initial from what was used.

The initial length = three 10' lengths = 30'

Length used = 13.75'

`\begin{gathered} \text{Conduit left = Initial length - length used} \\ \text{Conduit left }=\text{ 30 - 13.75} \\ =16.25 \\ \end{gathered}`

The total conduit he has left is

Answer: 16.25 feet
