Problema Solution

A construction crew is lengthening a road. The road started with a length of

53

miles, and the crew is adding

3

miles 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.

Answer provided by our tutors

The equation relating L to D is:

L = 53 + 3D

We need to find L when D = 37 days:

L = 53 + 3*37

L = 164 mi

The total length of the road after 37 days is 164 miles.
