---------------------------------
Draw the picture of the two trains moving in the same direction.
---------------
Train A DATA:
rate = 100 mph ; time = x hrs ; distance = rt = 100x miles
----------------------
Train B DATA:
rate = 120 mph ; time = x - (1/4) hr. ; distance = rt = 120x - 30 miles
==========================================
Equation:
distance A = distance B
100x = 120x - 30
20x = 30
x = 3/2 hrs
------------------------
Meeting time: 2:20 + 1 hr 30 min = 3:50
================================
Cheers,
