    You arrive at your school 5 minutes late if you walk with a speed of 4 km/h, but you arrive 10 minutes before the scheduled time if you walk with a speed of 5 km/h. The distance of your school from your house (in km) is

    A) 4                     

    B) 5

    C) 10                    

    D) 2

    Correct Answer: B

    Solution :

    If the required distance be \[=\text{ }x\]km, then \[\frac{x}{4}-\frac{x}{5}=\frac{10+5}{60}\] \[\Rightarrow \frac{5x-4x}{20}=\frac{1}{4}\] \[\Rightarrow \frac{x}{20}=\frac{1}{4}\] \[\Rightarrow x=\frac{1}{4}\times 20=5\] km.
