Two persons start from A and B, moving towards each other with a speed of 25 kmph and 49 kmph, respectively. After they cross each other, the person starting from B covers 145 km to reach A. What is the distance (in km) covered by A and B?
Solution(By Examveda Team)
A__________145 km_____________M_________X km_____________B
Let M be the meeting point. Its take time T to reach at M. Total distance = (145 +X) km.
Time taken by A = 145/25 hours. [as, Speed *time = Distance covered.]
Time taken by B = X/49 hours.
Since,
Time taken by = Time taken by B.
145/25 hours. = X/49 hours.
25X = 7105
X = 284.2 Km.
So Total Distance = 284.2 + 145 = 429.2 Km.
