    A person travels 600 km by train at 80 km/h, 800 km by ship at 40 km/h, 500 km by aeroplane 400 km/h and 100 km by car at 50 km/h. What is the average speed for the entire distance?

    A)  \[65\frac{6}{123}\text{km/h}\]

    B)         60 km/h

    C)  \[60\frac{5}{123}\text{km/h}\]  

    D)  62 km/h     

    Correct Answer: A

    Solution :

    Total time \[=\frac{600}{80}+\frac{800}{40}+\frac{500}{400}+\frac{100}{50}=\frac{246}{8}\,\,\text{h}\] Average speed \[=\frac{600+800+500+100}{\frac{246}{8}}\] \[=\frac{2000\times 8}{248}=65\frac{6}{123}\,\,\text{km/h}\]
