<PRE><B>Question 372867</B>
Train A New York  Boston 8.00 am- 65 mph - 
Train B Bost New York 9.00 am - 90 mph
..
Train A in 1 hour before train B started has traveled 65 miles.
Balnce distance = 220 -65 = 155 miles.
..
At this point distance = 155 miles.
travelling towards each other.
So add the speeds  90+65= 155 mph
..
t = d/r
t = 155/155 mph
..
t = 1hour after Train B leaves.
So at 10.00 am they cross each other.
