Question

A construction crew is lengthening a road that originally measured 43 miles.The crew is adding 1 mile to the road each day. Let L be the length in brackets in miles after the days over construction right in equation relating L to D then use this equation to find the length of the road after 15 days

Answer 1

The original measurement is 43 miles.

The rate is 1 mile each day.

Use this information, we can express the following

`L=1\cdot D+43`

So, for 15 days, we have

`L=1\cdot15+43=15+43=58`

Hence, after 58 days, the length of the road will be 58 miles.
