    Question

    Find the distance travelled (in km) by the truck to

    reach point B from point A, if a car cover 45% the same distance in 2 hours 42 minutes and a truck covers 60% of the distance in 6 hours. The sum of speed of the car and truck is 140 km/hr.
    A 525 km Correct Answer Incorrect Answer
    B 784 km Correct Answer Incorrect Answer
    C 834 km Correct Answer Incorrect Answer
    D 864 km Correct Answer Incorrect Answer

    Solution

    Let speed of car be s kmph
    Time taken by car travel total distance = 100/45 x 2.7 = 6 hrs
    Time taken by truck to cover total distance = 100/60 x 6 = 10 hrs
    so, s x 6 = (140 - s) x 10
    6s = 1400 - 10s
    so, riquired distance = 87.5 x 6 = 525 km
