Question

A construction crew is lengthening a road that originally measured 41 miles. The crew is adding one mile to the road each day.

Let L be the length (in miles) after D days of construction.

Write an equation relating L to D. Then use this equation to find the length of the road after 14 days.

Answer 1

41 + (D x 1) = L

Explanation:

To determine the necessary equation to lengthen a road whose initial measure is 41 miles, knowing that a new mile is built every day, the following equation must be performed:

41 + (D x 1) = L

Thus, if 14 days had passed, the length of the journey would be determined as follows:

41 + (14 x 1) = L

41 + 14 = L

55 = L

Therefore, after 14 days, the road's length will be 55 miles.
