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.
