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, \[\frac{x}{40}-\frac{x}{50}=\frac{15}{60}\] \[\frac{5x-4x}{200}=\frac{15}{60}\] \[\therefore \] \[x=\frac{15}{60}\times 200=50\,km\]You need to login to perform this action.
