Time(minutes)
30
40
50
60

Area (square feet)

4350
5800
7250
8700

What is the unit rate for the given table

Answer 1

To find the unit rate from the given table, we need to determine how much area (in square feet) is covered per minute.

We can calculate the unit rate by dividing the area by the time for each pair of values in the table:

1. For 30 minutes:
\[
\text{Unit Rate} = \frac{4350 \, \text{square feet}}{30 \, \text{minutes}} = 145 \, \text{square feet per minute}
\]

2. For 40 minutes:
\[
\text{Unit Rate} = \frac{5800 \, \text{square feet}}{40 \, \text{minutes}} = 145 \, \text{square feet per minute}
\]

3. For 50 minutes:
\[
\text{Unit Rate} = \frac{7250 \, \text{square feet}}{50 \, \text{minutes}} = 145 \, \text{square feet per minute}
\]

4. For 60 minutes:
\[
\text{Unit Rate} = \frac{8700 \, \text{square feet}}{60 \, \text{minutes}} = 145 \, \text{square feet per minute}
\]

From these calculations, we can see that the unit rate is consistent across all time intervals.

**The unit rate is 145 square feet per minute.**
