Two trains are 330 miles apart, and their speeds differ by 20 mph. Find the speed of each train if they are traveling toward each other and will meet in 3 hours.
-------------------
1st Train DATA:
distance: x miles ; time = 3 hrs ; rate = x/3 hrs
--------------------------------------------------
2nd Train DATA:
distance: (330-x) miles ; time = 3 hrs ; rate = (330-x)/3= 110-(x/3) hrs
------------------------------------------------
rate1 - rate2 = 20
(x/3) - [110-(x/3)] = 20
(2/3)x = 20 + 110
(2/3)x = 130
x = (3/2)130
x = 195 miles (distance traveled by 1st Train)
speed of Train1 = 195/3 = 65 mph
----------------
speed of Train2 = (330-195)/3 = 45 mph
===============================================
