Question 179888: I am really stuck on this problem and could use some help.
At noon a train leaves Los Angeles, headed for Las Vegas, a distance of 260 miles. The train travels at a speed of 60 mph. At 1p.m. a second train leaves Las Vegas headed for Los Angeles, traveling at 40 mph. How long after the train leaves Las Vegas will the two trains pass each other?
This is how I attempted to work it out:
1st train distance= 60(x+1), rate= 60mph, time= x+1
2nd train distance= 40x, rate=40mph, time=x
60(x+1)=40x
60x +60=40x
60 =-20x
-3 =x
The trains could not pass at -3 hours. I can't figure out what I'm doing wrong! Please help. :-)
