Question

If 0.8 square of shingles can be applied in 1 hour, how long will it take to apply 8.25 squares?

A. 10.31 hours
B. 10.5 hours
C. 10.75 hours
D. 11 hours

Answer 1

To determine the time to apply 8.25 squares of shingles at a rate of 0.8 squares per hour, divide 8.25 by 0.8 to get approximately 10.31 hours.

Step-by-step explanation:

The question is asking how long it will take to apply 8.25 squares of shingles if 0.8 square can be applied in 1 hour. To find the time taken to apply 8.25 squares, you can set up a proportion where 0.8 squares corresponds to 1 hour:

0.8 squares : 1 hour = 8.25 squares : x hours

To solve for x (the number of hours), divide 8.25 by 0.8:

x = 8.25 / 0.8

x = 10.3125 hours

This can be rounded to two decimal places, resulting in x being approximately 10.31 hours, which is answer A.
