A) 12:30 pm
B) 1:00 pm
C) 2:30 pm
D) 1:00 pm
Correct Answer :1:00 pm
Explanation :
Total distance between M and N= 569 km
First train leaves station at 8:00 am and second at 9:00 am. So first train i.e.,
from M to N has covered 53 km distance in 1 hour.
So, distance left between the stations = 569 − 53 = 516 km
trains are travelling in opposite directions. So, relative speed of trains = 53 + 76 = 129 km/h
Now, Time taken to cover 519 km = 519/129= 4 hours
Hence the time, at which both the trains will meet, is 4 hour after second train left i.e., 9:00 am + 4 h = 1:00 pm
