    A boat goes 40 km upstream in 8 h and 36 km downstream in 6 h. The speed of the boat in still water is

    A)  6.5 km/h                      

    B)  5.5 km/h

    C)  6 km/h            

    D)  5 km/h

    Correct Answer: B

    Solution :

    Speed upstream\[=\frac{40}{8}=5\,\text{km/h}\] Speed downstream \[=\frac{36}{6}=6\,\text{km/h}\] \[\therefore \] Speed of boat in still water             \[=\frac{1}{2}(5+6)=5.5\,\text{km/h}\]
