Question

In 2014, County X had 783 miles of paved roads. Starting in 2015, the county has been building 8 miles of new paved roads each year. At this rate, how many miles of paved road will County X have in 2030? (Assume that no paved roads go out of service.)

Answer 1

County X will have 903 miles of paved road in 2030.

Step-by-step explanation:

To calculate the number of miles of paved road County X will have in 2030, we need to determine how many miles of new roads will be built from 2015 to 2030 and add that to the initial 783 miles. From 2015 to 2030, there are 15 years, so we can multiply the number of new miles built each year (8 miles) by the number of years (15) to get the total additional miles of paved road. 8 miles/year * 15 years = 120 miles. Finally, we add the initial 783 miles and the additional 120 miles to get the total number of miles in 2030: 783 miles + 120 miles = 903 miles.
