    A and B start at the same time with speeds of 40 km/h and 50 km/h respectively. If in covering the journey A takes 15 min longer than B, the total distance of the journey is

    A)  46 km             

    B)  48 km

    C)  50 km 

    D)  52 km

    Correct Answer: C

    Solution :

    Let the distance be x km Time taken by \[A=\frac{x}{40}\,h\] Time taken by \[B=\frac{x}{50}\,h\] Now, \[\frac{x}{40}-\frac{x}{50}=\frac{15}{60}\]             \[\frac{5x-4x}{200}=\frac{15}{60}\] \[\therefore \]      \[x=\frac{15}{60}\times 200=50\,km\]
