    A person goes from a place A to another place B at the speed of 4 km/h and returns at a speed of 3 km/h. If he takes 7 h in all, then what is the distance between the two places?

    A) 12 km  

    B) 8 km      

    C) 6 km                            

    D) 5 km

    Correct Answer: A

    Solution :

    \[\text{Time=}\frac{\text{Distance}}{\text{Speed}}\] Let distance travel by person from A to B be x km \[\therefore \] \[7=\frac{x}{4}+\frac{x}{3}=\frac{x(3+4)}{12}=\frac{7x}{12}\] \[\Rightarrow \] \[x=12\,\text{km}\]
