Final answer:
The total time required to build a 15-foot-high wall, given the company has constructed 6 feet in 2 hours, is 5 hours. This calculation is based on the constant rate of construction.
Step-by-step explanation:
The student's question involves calculating the total time needed to complete a task given a certain rate of progress. To find out how many total hours will be required to complete the construction of a brick wall, we can use a proportion based on the rate of work already done. The construction company has built 6 feet of the wall in 2 hours. Therefore, since the total height of the wall is 15 feet, we can set up a ratio to find the total time needed.
The proportions set would look like this:
2 hours/6 feet = x hours/15 feet
Solving for x gives us:
x = (2 hours * 15 feet) / 6 feet
x = 30/6
x = 5 hours
Therefore, it will take a total of 5 hours to complete the wall if the company continues at the same rate.
