    A car travels 300 km in 5.5 hrs and another 400 km in 5.5 hrs. Find the average speed of the car during the entire journey.

    A) 46km/hr          

    B)         50km/hr

    C) 49 km/hr         

    D)         60 km/hr

    Correct Answer: B

    Solution :

        Total distance travelled = 300 + 400 = 700 km Total time taken = 5.5 + 8.5 = 14hrs. Total distance travelled \[\therefore \]  Average speed \[=\frac{\text{Total}\,\text{distance}\,\text{travelled}}{\text{Total}\,\text{Time}\,\text{taken}}\] \[=\frac{700}{14}=50\,km/hr\].
