    A boy goes to his school from his house at a speed of 3 km/h and returns at a speed of 2 km/h. If he takes 5 h in going and coming, the distance between his house and school is

    A)  6 km               

    B)  5 km

    C)  5.5 km            

    D)  6.5 km

    Correct Answer: A

    Solution :

    Let required distance be x km. Then, \[\frac{x}{3}+\frac{x}{2}=5\] \[\Rightarrow \]   \[\frac{2x+3x}{6}=5\] \[\Rightarrow \]   \[5x=6\times 5\] \[\therefore \]      \[x=\frac{6\times 5}{5}=6\,km\]
