Question 350071: A train leaves Perryville at 6:00 AM and travels east at a rate of 64 mph. As it reaches its destination, Granite City, a westbound train departs from Granite City for Perryville, traveling at a rate of 48 mph. How far is it from Perryville to Granite City by train if the westbound train gets to Perryville at 9:30 AM?
I tried making a chart and I know that one has to complete its trip before the other begins thus making two entire trips. Train 1 travels at 64 mph and Train 2 travels at 48 mph and they both complete the distance in 210 minutes. Distance=Rate*Time so the problem is essentially two problems with their answers added together (correct?) but the issue is what to use in the time box of my chart. Distance is blank and is RT with RT containing a variable. How do I find out what goes in the time box? how do I find the distance traveled by both trains and the time it took each train to complete the trip?
Thanks so much!!! :)

Question 350435: Emily leaves home at 2:00 traveling 30 miles per hour. Sarah leaves 20 mins. later traveling at 36 miles per hour. At what time will they meet up.
I think it has something to do with t=r/d but the question does not give distance. I also tried at table 30t+36(t+20)= ____ but I don't know what to put in the blank. Please help me. Thank you for you time.

Question 350497: First off, thanks for volunteering your time and expertise to help students; you are so valuable to us!
Two brothers , Bob and Charlie , live 450 miles apart. Starting at the same time they plan to drive until they meet. Bob averages 10 mph faster than Charlie who averages 50 mph. How long will it take them to meet?
Let t = time (in hours)
60(t) + 50(t) = 450
t = 4.09 hours
I have a very bad history with converting a word problem into a math problem, so I am not too confident in my solution.

1. An earthworm of length 15cm is crawling along at 2cm/s. An ant overtakes the worm in 5 seconds. How fast is the ant walking?
Ans. The speed of the ant is 15/5 =3 cm/s.
The earthworm is moving at the speed of 2 cm/s. Therefore, the speed of the ant will be 3 plus 2 = 5cm/s.
2. A car completes a journey at an average speed of 40km/h. At what speed must it travel on the return journey if the average speed for the complete journey (out and back) is 60km/hr?
