Question: 1 / 745

If installation rate is 6.37 squares per day, how long will it take to install 47 squares of shingles?

5.67 days

6.67 days

7.37 days

To determine how long it will take to install 47 squares of shingles at a rate of 6.37 squares per day, you can use the formula:

Total number of squares ÷ Installation rate = Time required in days.

So, you take the total squares, 47, and divide it by the installation rate of 6.37 squares per day:

47 squares ÷ 6.37 squares/day = approximately 7.37 days.

This calculation shows that if you install shingles at a consistent rate of 6.37 squares each day, you would complete the installation of 47 squares in about 7.37 days.

This choice reflects a realistic estimate based on the daily output, factoring in the continuous nature of installation work. It highlights the importance of understanding how to manipulate the relationship between total task size and rate of work to estimate time effectively.
