Question

Sebastian mowed 9 lawns in 15 hours. Fill out the table
Hours Lawns
3
15 9
20

Answer 1

To fill out the table for hours and lawns mowed, we start by finding the rate at which Sebastian mows lawns.

Given that Sebastian mowed 9 lawns in 15 hours, we can calculate the rate of lawns per hour:

\[
\text{Rate} = \frac{9 \text{ lawns}}{15 \text{ hours}} = 0.6 \text{ lawns per hour}
\]

Now, we can fill out the table based on this rate.

1. **For 3 hours:**
\[
\text{Lawns} = 0.6 \text{ lawns/hour} \times 3 \text{ hours} = 1.8 \text{ lawns}
\]

2. **For 15 hours:**
This is already filled out (9 lawns).

3. **For 20 hours:**
\[
\text{Lawns} = 0.6 \text{ lawns/hour} \times 20 \text{ hours} = 12 \text{ lawns}
\]

Now, putting it all together, the completed table looks like this:

| Hours | Lawns |
|-------|-------|
| 3 | 1.8 |
| 15 | 9 |
| 20 | 12 |
