    A walks at a uniform rate of 4 km an hour and 4 h after his start, B bicycles after him at the uniform rate of 10 km an hour. How far from the starting point will B catch A?

    A)  16.7 km                       

    B)  18.6 km

    C)  21.5 km                       

    D)  26.7 km

    Correct Answer: D

    Solution :

    Distance covered by A in h \[=4\times 4=16\,km\] Relative speed of B with respect to \[~A=10-4=6\,\text{km/h}\] \[\therefore \] Time taken to catch\[~A=\frac{16}{6}=\frac{8}{3}h\] \[\therefore \] Required distance\[=\frac{8}{3}\times 10=\frac{80}{3}=26.7\,km\]
