I am thinking C
Why? Because for every 3 hours Brook drove 180 mile so divide it by 3 and you get how many miles she drove for 1 hour. Same goes for Diederick for every 4 hours he drove 160, so divide 160 by 4 to get miles per 1 hour. You must subtract to find the difference between the two, subtracting is a great way to compare numeric values. Hope this helped!
 
C. because step 1 you have to divide 180 and 3. Step 2 you have to divide 160 and 4. Step 3 you have to subtract the two quotients. Hope this helps
