Answer:

Alexis will wash 14 windows in 1 hour.

Step-by-step explanation:

We are given the following information in the question.

Number of windows washed = $10\displaystyle\frac{1}{2}$

Time taken to wash the windows = $\displaystyle\frac{3}{4} \text{ hours}$

We have to find:

Number of windows washed in 1 hour=

Formula:

$\text{Windows washed in 1 hour} = \displaystyle\frac{\text{Total windows washed}}{\text{Time taken to wash windows}}=\frac{10\frac{1}{2}}{\frac{3}{4}}\\\\=\frac{21\times 4}{3\times 2} = 14$

Thus, Alexis will wash 14 windows in 1 hour.
