word problem:

b) number of days in a week
c) distance from Centerville to Westfield
d) number of miles driven on the seventh day.
I picked d.
is that right?

Yes, that is correct. In order to calculate the average miles driven each day for the week, you need to know the total amount of miles driven during the entire 7-day period. That total number would be the sum of miles driven on the first 4 days, the 250 miles driven on Friday, the 150 miles driven on Saturday, and the number of miles driven on the seventh day.
