Relative running time
CMAT 2020 · Quantitative Techniques & Data Interpretation · Medium · Speed Time Distance
X and Y are running towards each other from their houses. X can reach Y's house in 25 minutes which is half the time taken by Y to run from his house to X's house. If the two start to run towards each other at the same time, then how much more time it will be required by Y to reach the middle of houses ?
- A.
18 min.
- B.
25 min.
- C.
50 min.
- D.
12.5 min.
D
Explanation
Time taken by X to cover full distance = 25 minutes. Time taken by Y to cover full distance = 50 minutes.
Time taken by Y to reach the midpoint = minutes. Time taken by X to reach the midpoint = minutes.
Additional time required by Y compared to X to reach the middle = minutes.
