turtlespeed 212 #51 August 20, 2003 Quote You have decided to take a morning run to prepare for the local marathon at an average speed of 6 miles per hour. Unfortunately, you are not in as good shape as you thought, and you are running uphill. You find that for the first half of the run, all uphill, your average speed was only 3 miles per hour. How fast must you run on the way back, all downhill, to make for an entire round trip average speed of 6 miles per hour? reply] 1) Morning run...Not factoring in temperature variations, wind velocity, or resistance that might elongate the distance....just a "strait forward math problem" 2) "You find that for the first half of the run" = equal time (ie 1/2 of run @ 3 MPH and the second 1/2 of run at xMPH) 3) Distance is irrelavent(sp) 4) So... if 1st half of run is say given a value of 1 hour, then the distance travelled is 3 miles. 5) if 6 miles an hour is the average that we are trying to achieve then we must run at 9MPH for tyhe next hour to cover 9 miles. 6) IF that is accomplished, then 3 miles in the first hour, and 9 miles in the second hour, is 12 miles in a two hour run...right? Last time I checked if you went 12 miles in two hours, the average was 6 miles an hour. 7)Now that I have wasted my time typing this, you are going to tell me that you meant distance not time...which in effect does make me 1/2 right.I'm not usually into the whole 3-way thing, but you got me a little excited with that. - Skymama BTR #1 / OTB^5 Official #2 / Hellfish #408 / VSCR #108/Tortuga/Orfun Quote Share this post Link to post Share on other sites Jib 0 #52 August 20, 2003 7mph. I'm guessing since you're only 1/2 way there, you still have to keep going another half and then come back.

OK, look Mr. Smartypants, if you're gonna be all brainiacal with us, you gotta at least specifiy that "half the run" refers to half of a set time limit as opposed to distance.

Time and distance are there to help figure out the answer but not completely relvant to the answer as different values can be used to determine the answer. No matter what the distance is, if you go 1/2 X-mph of the target for the first half unless you can instantly go back to the start you cant get back in time to average X-mph for the entire run.....no matter whatthe distance Now for another one, non-math this time......
