Introduction

As the winter months approach, many people are looking for ways to earn extra money. For Melinda and Paula, shoveling driveways and sidewalks is a great way to do just that. In this article, we will explore their shoveling challenge and use mathematical concepts to analyze their work.

The Initial Shoveling Challenge

Melinda and Paula started their shoveling challenge by working together to clear 450 square feet of sidewalk in just 30 minutes. This is an impressive feat, and it's clear that they are a well-oiled machine when it comes to shoveling.

Calculating Their Combined Rate

To calculate their combined rate, we need to divide the total area they shoveled (450 square feet) by the time it took them to do it (30 minutes). This gives us a rate of 15 square feet per minute.

Melinda and Paula's Individual Rates

After completing the initial challenge, Melinda and Paula decided to work individually to see who could shovel the most area in a set amount of time. Melinda shoveled for 20 minutes, while Paula shoveled for 25 minutes. Together, they completed 345 square feet of sidewalk.

Calculating Melinda's Rate

To calculate Melinda's rate, we need to divide the area she shoveled (345 square feet) by the time it took her to do it (20 minutes). This gives us a rate of 17.25 square feet per minute.

Calculating Paula's Rate

To calculate Paula's rate, we need to divide the area she shoveled (345 square feet) by the time it took her to do it (25 minutes). This gives us a rate of 13.8 square feet per minute.

Comparing Their Rates

Now that we have calculated Melinda's and Paula's individual rates, we can compare them to their combined rate. We can see that Melinda's rate (17.25 square feet per minute) is higher than their combined rate (15 square feet per minute), while Paula's rate (13.8 square feet per minute) is lower.

Why the Difference?

There are several reasons why Melinda's rate is higher than their combined rate. One reason is that Melinda is more efficient at shoveling than Paula. Another reason is that Melinda is able to work at a faster pace than Paula, which allows her to complete more area in the same amount of time.

Conclusion

In conclusion, Melinda and Paula's shoveling challenge is a great example of how mathematical concepts can be applied to real-world situations. By calculating their combined rate and individual rates, we were able to analyze their work and understand why Melinda's rate is higher than their combined rate. This is a valuable lesson for anyone looking to improve their productivity and efficiency.
