    A truck covers a certain distance in 8 h at the speed of 63 km/h. What is the average speed of a car which travels a distance of 120 km more than the truck in the same time?

    A) 78 km/h

    B) 72 km/h

    C) 84 km/h

    D) 88 km/h

    Correct Answer: A

    Solution :

    [a] \[\therefore \] Distance covered by truck in \[8\,h=63\times 8=504\,km\] and distance covered by car in 8 h \[=504+120\] \[=624\,km\] Hence, speed of car \[\frac{\text{Distance}\,\,\text{covered}}{\text{Time}\,\,\text{taken}}\] \[=\frac{624}{8}=78\,km/h\]
