A construction crew is lengthening a road that originally measured 45 miles. the crew is adding 1 mile to the road each day let l be the length (in mile) after the days of construction write an equation relate relating L to D then use this equation to find the length of the road after 23 days
equation
Length of the road after 23 days______miles
The equation relating the length of the road (L) to the number of days of construction (D) is:
L = 45 + D
To find the length of the road after 23 days, we substitute D = 23 into the equation:
L = 45 + 23
L = 68
Therefore, the length of the road after 23 days of construction is 68 miles.
