QUESTION: 224

Two cars are traveling on the same road towards each other. If car A is traveling at a speed of 120 Km/h and car B is traveling 15% slower, how much time will it take the cars to meet if the initial distance between the two is 668.4 Km and car A started to drive one hour and a half before car B started?

one hours and 30 minutes.
two hours.
two hours and 12 minutes.
three hours and 15 minutes.
three hours and 18 minutes.

Answer(s): C

Explanation:

Car B is traveling at a speed of 0.85 x 120 = 102 Km/h.
Car A travels alone a distance of 120 x 1.5 = 180 Km. The remaining distance should be divided among the sum of the cars speeds: (668.4 – 180 = 488.4 Km) / (102 + 120) = 2.2 = Two hours and 12 minutes.
