In that 1 hour(s) from 4 to 5 the first train has gone 40 miles
which reduces the distance by 40 miles to a new distance of 160 miles
(40+40)*t=160
(80)*t=160
t=160/80
t=2 hours
2 hours
00 minutes
00 seconds
time =2:00:00
time =2:00 pm rounded
The train pass or meet at 7:00:00 pm
The train pass or meet at 7:00 pm rounded
