Answer:
Let the distance they meet after start be x
d= rt Or t= d/r
time taken by one train = x/100
time taken by other train = (75-x)/80
These two times are same
x/100 = (75-x)/80
80x=100(75-x)
80x=7500-100x
80x+100x=7500
180x= 7500
x= 41.67 km
time they meet = 41.67/100
=0.42 hours= 25 minutes
they will cross at 8:25 AM
