This one I really don't know how to figure it out, here is what I know...
Two trains are approaching one another on a collision course. One is going 60 mph and the other is going 90 mph. They will collide in 20 minutes. How far apart are they now?
I know 60 and 90 mph is the rate and 20 minutes is the time? I'm just totally confused, Can someone please help? Thank you!
