The distance between Delhi and Meerut is 75km . Two trains at a speed of 100km/hr and 80km/hr leave the two stations at 8am towards each other. At what time they will pass each other?

math 
Steve,
the two trains close the distance at 180km/hr. So, they will take 75/180 hr = 25 min to meet.
time will be 8:25 am
Let's hope they are on separate tracks!
