Solution:

When 2nd train starts i.e. at 7 AM (1 hr after 6 AM ), distance covered by first train is 60 km (i.e. in 1 hr).
Now 2nd train also starts and distance between them is now

(480-60) = 420

km
Both coming in opposite direction, so relative speed

= (60+80) = 140

km /hr
So time = 7:00 AM +

(420/140)

= 7:00 AM+3 hrs = 10:00 AM
