A train M leaves Meerut at 5 a.m. and reaches Delhi at 9 a.m. Another train N leaves Delhi at 7 a.m. and reaches Meerut at 10:30 a.m. At what time do the two trains cross each other?
A
8:26 a.m.
B
8:00 a.m.
C
7:36 a.m.
D
7:56 a.m.
Correct Option:
D
Explanation
The Physics: Let distance = 28 km. Speeds are 7 km/h and 8 km/h. By 7:00 a.m., Train M has covered 14 km, leaving 14 km. Relative speed = 15 km/h, so meeting time is 14/15 hour = 56 minutes after 7:00 a.m., i.e. 7:56 a.m.
