Kristy, Amy, and Blair are going on a cross-country road trip from Washington to Maine. The total driving time is 48 hours. Each driver will drive 6 hours daily and in the remaining hours of the day the group will sight-see and explore. They will sleep in the car when they are not driving. They all have driver's licenses, but Amy is scared of driving in unfamiliar places and would prefer not to take the wheel. How much sooner would the group arrive in Maine, in hours, if Amy chose to drive, compared to just Kristy and Blair?	Choose the correct choice from the following answers
A) 12
B) 24.76
C) 31.92
D) 36.92
E) 24
All three girls calculation: 3 girls x 6 hours = 18 hours of driving per day, 6 nondriving hours/day   48 total trip hours divided by 18 daily driving hours = 2.67 days / driving rotations   2.67 x 24 (hours in one day) = 64.08 total hours for road trip   2 girls calculation: 2 girls x 6 hours = 12 hours of driving per day, 12 nondriving hours/day   48 total trip hours divided by 12 daily driving hours = 4 days / driving rotations   4 x 24 (hours in one day) = 96 total hours for road trip   FINAL ANSWER: 96 hours (2 girls total) minus 64.08 (3 girls total) = ANSWER 31.92: The group would arrive in Maine 31.92 hours sooner if all three drove.
