    A)  \[12\frac{1}{2}\]km/hr  

    B)  13 km/hr

    C)  15 1/8 km/hr    

    D)  20 km/hr

    Correct Answer: A

    Solution :

    [a] Total Distance =100 km Distance travelled in first 2hr \[=2\times 20=40\] Remaining distance \[=100-\,40=60\,\,km\] Time taken = \[\frac{60}{10}=6hr\] \[Av\,\,speed=\frac{Total\,\,dis\tan ce}{Total\,\,time}=\frac{100}{8}=12\frac{1}{2}\,\,Km/hr\]
