<PRE><B>Question 1027118</B>
Trian A leaves Bosotn for NY at 7 am going 30mph. Trian B leaves NY for Boston at 8:30 am going 80mph. If the distance from Boston to NY is 210miles when did the trains pass each other? 
-----
Bos to NY DATA:
rate = 30 mph ; time = x hrs ; distance = 30x miles
-------
NY to Bos DATA:
rate = 80 mph ; time = x-(3/2) hrs ; distance = 80(x-(3/2) miles
-------
Equation:
30x + 80(x-(3/2)) = 120 miles
30x + 80x - 120 = 120
110x = 240
x = 24/11 = 2 2/11 hrs = 2hr 10 min 54 sec
-----
Ans: Time = 7:00 + 2hr 10min 54 sec = 9:11AM when rounded up
