Two stations A and B are 110 km apart on a straight line. One train starts from A at 7 a.m. and travels towards B at 20 kmph. Another train starts from B at 8 a.m. and travels towards A at 25 kmph. At what time will they meet?
A
9 a.m.
B
10 a.m.
C
11 a.m.
D
10:30 a.m.
Correct Option:
B
Explanation
By 8 A.M., the first train has travelled 20 km, leaving 90 km. Combined speed = 20+25=45 km/h. 90/45=2 hours, so they meet at 10 A.M.
