Zelda -These word problems may seem tricky, but the key to solving them is simply writing down everything you know and then sit back and see if you "see" a solution.Here is what we know:(1) Mary is running at 600 f/m(2) She runs for 4 minutes before Jim starts to run.  (3) So, how far did Mary run before Jim started?  Well, if she runs 600 feet in one minute, then is 4 minutes she ran 600 x 4 = 2400 feet.(4) Jim can run at 800 f/m(5) If Jim runs at 800 f/m, then he is running how much faster than Mary?  Well, that would be: 800 - 600 = 200 f/m(6) So, Jim is catching up to Mary at 200 f/m.7) So, if Mary is ahead by 2400 feet (see step 3), how long will it take Jim to catch up if he is catching up at 200 f/m?8) Here is the final equation:2400 = 200t, where t is the number of minutes to catch up.I'll leave it up to you to finish up the problem.  And, I hope you learned a little bit about solving this type of problem.Good Luck

when will that ever come in handy later on in life ;)
