Q:
A) 12 a.m. | B) 1 p.m. |
C) 11 a.m. | D) 12 p.m. |
Answer: D) 12 p.m.
Explanation:
Explanation:
Assume both trains meet after 'p' hours after 7 a.m.
Distance covered by train starting from A in 'p' hours = 20p km
Distance covered by train starting from B in (p-1) hours = 25(p-1)
Total distance = 200
=> 20x + 25(x-1) = 200
=> 45x = 225
=> p= 5
Means, they meet after 5 hours after 7 am, ie, they meet at 12 p.m.
