Quizplus · Accepted Answer

Car A will reach Atlanta first after driving for a little less than three and one quarter-days (three days, 6 hours) and Car B will reach Atlanta about 10 hours later after driving three and two third-days (three days, 16 hours). Car A travels 680 miles each day; Car B travels 600 miles each day. 2,200 miles divided by 680 miles-per-day is 3.235 days of driving for Car A. 2,200 miles divided by 600 miles-per-day is 3.667 days of driving for Car B.
