 * Teams 1 & 2**

The answer is 25 miles. Figure out how long it takes the horses too meet, I then figured out how long it would take the fly and came u with 25. GO BOB!

This is Bob (copied): 1** =] In 7th grade math class, we created Bob and Mob... Okay. In team 1, we found out that it took 1 hour for the horses to meet. Back to the question, the fly flies 25 miles per hour. So if the fly flew 1 hour, it should fly 25 miles. =]

YAY Applause... || ** Team member 2 ** *gasps* I remember BOB!!! :D AHAHAHAHAHAH. And he had his own seat!!! That cute little guy. (on a piece of paper) Good memories... Okay, sorry, I'm not using this space productively.

^ ^ ^ AHHHH!!! It's Bob!!! :D Long time no see! Good ta see ya little guy. Here's a picture I created of the problem. Once again, I apologize for the shrinking of your spaces. :] It would be unclear if it were any smaller.

I solved the problem the same way you did Team Members 1 and 4. I found out how long it would take the horses to meet, which was 1 hour, and in one hour, the fly would fly 25 miles. Does anyone have an idea for how we can justify our answer? || ** Team member 3 ** I remember bob too!! hahah yayyy! good times!

I solved the problem the same way as team member 1. They would meet in one hour and in one hour the fly would fly 25 miles. Thanks for the picture it helped. I know what the answer is and I undersatnd how to get it, but if you can, can someone help explain how to check the work! Thank you! =) || ** Team member 4 ** Ok honestly i don't know who Bob is but that's not the point.The first horse is moving at 8 mph and the second horse is moving at 7 mph. You would need to set up an equation 7x + 8x = 15 then you would need to solve it. 7 + 8 = 15 15x = 15 15x/15 =15/15 x=1 if it takes the horses 1 hour to meet, and the fly is flying at a speed of 25 mph, the fly will have flown 25 miles when the horses have finally met. Thank you... Thank you... Hold your applause... =) || 5**

I set up a chart to figure the problem out. I got the same equation as team member 4. (7x + 8x = 15. 7 + 8 = 15 15x = 15 15x/15 =15/15 x=1) This is because the horses start 15 miles apart. Since one horse travels 8mph and the other horse travels 7mph. I just dont understand how to check this problem. || **Team member 6** || **Team member 7** || **Team member 8** I was confused about this POTM until team member two thourougly explained it to me. Think of it as instad of the horses going its you in a car and just replace that as in your final answer as a horse. I also got what team member 1 and 2 got becuase I drew apicture but much more hideous and it took me awhile. I got thiis problem wrong the first time becuase I made a silly mistake by adding for the fly's time instead of not counting it. (good job by team member two but just make sure they understand the fly lost no time in the turn) (-_-) ||

Two horses approach each other along the same country road, one walking at 8 mph, and the other at 7 mph. When the horses are 15 miles apart, a horsefly leaves one horse and flies at 25 mph towards the other. No sooner does the fly reach that horse than it turns around (losing no time on the turn) and returns to the first horse. If the fly continues to fly back and forth between the approaching horses, how far has the fly flow when the horses meet?  You must use D=R*T to solve this problem I have the answer I think but I am just not really sure how to solve it I am almost there.  How far has the fly flown when the horses meet? The fly flew 25 miles when the horses meet. Let x = the number of hour(s) needed for the horses to meet. 7x+8x = 15 miles to get when the time needed for the horses to meet. we combine like terms: 15x = 15 Then we get the x alone by dividing 15. 15x/15 = 15/15 x=1 It takes 1 hour for the horses to meet. The question is looking for how many miles the fly flew by the time the two horses meet. If the fly flies 25 miles per hour, the fly flies 25 miles in 1 hour. 25(1)=25

7x + 8x = 15 x=1 (1 hour when they meet) 25(1) = 25 (25 miles!)

It is correct, because the fly can only fly 25 miles no matter how many turns the fly took. (25 mph) Another way of doing this problem is to draw a chart/picture that represents the horse traveling and the fly flying toward the horse and back then going again until the horses meet. I think that would take too much time to do, because i kept getting weird numbers such as 1.6903409 miles with the bar on top of 09. Here's a way to solve the problem using a picture: It's not done, but I believe that if you keep graphing it we will get 25 miles flown for the fly, too.
