B. because we know everything else but that we would have to do math to figure it out. Read the question.
But your question asks, "What is the unknown quantity? "

"How many DAYS will it take them to finish?"
That was not the answer! I JUST checked! Ugh.
You are correct, the unknown quantity in this question is the number of days it will take the paving crew to finish. To find this, we need to consider the total distance that needs to be paved and the rate at which they can pave per day.
According to the information given, the total distance that needs to be paved is 30 miles, and 6 miles have already been completed. The paving crew can complete 3 miles of paving per day.
To find the number of days it will take them to finish, we can use the formula:
Number of days = (Total miles to be paved - Miles already completed) / Miles paved per day
Substituting the given values, we have:
Number of days = (30 - 6) / 3 = 24 / 3 = 8
Therefore, it will take the paving crew 8 days to finish paving the remaining 24 miles.
So, the correct answer is B. The days it would take to finish paving.
