Aubrey and charlie are driving to a city that is 120 mi from their house. they have already traveled 20 mi, and they are driving at a constant rate of 50 mi/h. complete the function that models the distance they drive as a function of time. then complete a reasonable domain for this situation.

30m

Step-by-step explanation:

First, i would calculate how much can 1 person build in a day:

If it takes 12 people 3 days to build a 72m, it would take (12x3) people to build 72m in 1 day

Or 36 people.

Then 1 person can build 72/36 meters of fence each day

Or 2 meters, so 15 people can build 30m of fence  )15x2)
