How long would it take the slower car to travel the distance XY? A 6 hours B. 8 hours C. 10 hours D. 12 hours E. 15 hours Let the distance between X and Y = 12 miles. Since the distance traveled by the faster car in 4 hours = (2/3)(12) = 8 miles, the distance traveled by the slower car in 4 hours = (total distance) - (distance traveled by the faster car) = 12-8 = 4 miles. Since the slower car travels 4 miles in 4 hours, the rate for the slower car = d/t = 4/4 = 1 mile per hour. Since the rate for the slower car = 1 mile per hour, the time for the slower car to travel the entire 12 miles = d/r = 12/1 = 12 hours. The correct answer is D. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.

Let's see: If it took to car B 4 hours to travel 1/3 of the distance, then it will take 8 hours to travel (2/3) of the distance. So, it takes 12 hours (4 hours 1/3, 8 hours 2/3) to travel form X to Y. I hope this explanation may help you. I'm available if you'd like a follow up.
