A construction crew is lengthening a road that originally measured 45 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.
Wait, if 45+D is 45, then wouldn't D be 0?
A construction crew is lengthening a road that originally measured 41 kilometers. The crew is adding one kilometer to the road each day. The length, L (in kilometers), after d days of construction is given by the following. =L+41d What is the length of the road after 13 days?
To write an equation relating L to D in this scenario, we can use the equation:
L = 45 + D
This equation states that the length L of the road is equal to the initial length of 45 miles plus the number of days D on which the construction crew added one mile each day.
To find the length of the road after 14 days, we substitute D = 14 into the equation:
L = 45 + 14
L = 59
Therefore, the length of the road after 14 days of construction is 59 miles.
What part of my answer to this same question, which
you posted before, did you not like?
45 + D = 45 + 14 = L
Solve for L.
