Question 26251: The word problem reads: a train leaves town a for town b, traveling at 35 mph. at the same time, a second train leaves town b for town a at 45 mph. if the two towns are 320 miles apart, how long will it take for the two trains to meet.
i did 35x=320:x=9, 45x=320:x=7:: i figured 9 hours was the answer. i am not sure. these word problems are tricky for me.

80x=320
x=4

Hence, it will take them 4 hours to meet.
