To solve the problem, we need to calculate how many square meters Jessica can wax per hour based on the given rate.

The problem states:
- Jessica waxes 20 m² of floor in \(\frac{3}{5}\) of an hour.

To find out how many square meters she waxes per hour, we can set up a proportion:
\[
\text{Rate} = \frac{\text{Area waxed}}{\text{Time taken}} = \frac{20 \, \text{m}^2}{\frac{3}{5} \, \text{hours}}.
\]

To simplify this, we divide 20 by \(\frac{3}{5}\). Dividing by a fraction is the same as multiplying by its reciprocal:
\[
\text{Rate} = 20 \times \frac{5}{3} = \frac{100}{3}.
\]

So, Jessica can wax:
\[
\frac{100}{3} \approx 33.33 \, \text{m}^2 \, \text{per hour}.
\]

Thus, Jessica can wax approximately **33.33 m² per hour**.

Here are five related questions to deepen your understanding:
1. How would the rate change if Jessica waxed 30 m² in \(\frac{3}{4}\) of an hour?
2. What is the general formula for calculating the rate of work based on time and area?
3. How much time would it take for Jessica to wax 50 m² at this same rate?
4. How would the problem change if Jessica waxed 20 m² in \(\frac{1}{2}\) of an hour instead?
5. How many square meters would Jessica wax in 2 hours at the same rate?

**Tip:** When dividing by fractions, remember that you multiply by the reciprocal of the fraction.

Jessica is a custodian at Oracle Arena. She waxes 20 m² of the floor in 3/5 of an hour. Jessica waxes the floor at a constant rate. At this rate, how many square meters can she wax per hour?

Find out how to calculate how many square meters Jessica can wax per hour based on a rate of 20 m² in 3/5 of an hour. This problem involves key mathematical concepts of proportions and rate of work, suitable for students in Grades 6-8.
