A construction crew is lengthening a road. The road started with a length of 54 mlles, and the crew is adding 4 mlles to the road each day.
Let L represent the total length of the road (in miles), and let D represent the number of days the crew has worked. Write an equation relating L to D. Then use this equation to find the total length of the road after the crew has worked 37 days.


Equation:

Total length of the road after 37 days:___miles

Respuesta :

The equation that relating the total length of the road L and the number of days D is L = 54 + 4d, the length of the road after 37 days is 202 miles

The length of the road at starting = 54 miles

The rate of lengthening the road per day = 4 miles per day

Where L is the total length of the road in miles

D is the number of days the crew has worked

Then the equation will be

L = 54 + 4D

The number of days = 37 days

Substitute the value of D

L = 54 + 4×37

L = 54 + 148

L = 202 miles

Hence, the equation that relating the total length of the road L and the number of days D is L = 54 + 4d, the length of the road after 37 days is 202 miles
