Chapter 6.3, Problem 2CYU

To determine

To find: How many inches, L can paint in one minute.

Answer to Problem 2CYU

L can paint 3 inches of fencing in one minute.

Explanation of Solution

Given information: 

Total fencing done by L in one hour is 5 yards.

Concept used:

Use following conversion formulae first:

  $1\text{ yard }=36\text{ inches}$

  $1\text{ hour }=60\text{ minutes}$

Then divide total inch, she can paint from total minutes painted.

Calculation:

Using above conversion formula,

5 yards $=5\times 36=180$ inches

So, a total inch painted in one minute is calculated as follows:

  $\begin{array}{c}\Rightarrow \frac{180}{60}\\ =3\text{in}\end{array}$

Thus, L can paint 3 inches of fencing in one minute.
