Off-topic discussion. Wanna talk about corsets, duct tape, or physics? This is the place. Detailed discussion of any current-season TV must be whitefonted.
Yes, this should be easy. Apparently, however, I got it all wrong.
Actually for the problem as written, if you take the average speed of the plane while it's accelerating or decelerating times the time it accelerates or decelerates, and add that the distance traveled while it's cruising, you should get the answer they're looking for.
Or what tommy said.

So many redundancies in the line I don't know where to start.
Emily, I don't have a clue as to your math problem, but just reading it made me feel all tingly.
Yay for TV-less Tuesday! "Washing the dog" sounds like fun. Is that like the "LUNCH" thing?

No, that's the "crazy hot sex" thing, which is for AFTER we wash the dog.
Okay, you all are getting the same kind of answer I got. Which makes me feel better, at least. Who knows, maybe they got it wrong, or maybe I read the wrong answer? Will check back in with an update. Am currently working on a practice test for the GRE Math subject test, which... ugh. I mean, I covered all this stuff in CS classes, but... well, a lot of it was in that class I failed. So as painful as it will be, I think I'd better go track down the book. er, if I still have it. Crap.

Hmmm.

Okay, -t, so let's say we've got a graph of airplane velocity. From time 0 to time 0.5 (hours) it goes directly up from 100 to 600 mph. From 0.5 to 3.5 it does 600 mph. From 3.5 to 4.5 it goes directly down from 600 to 100 again. What's the total distance it travels, and how do you go about getting it?
If by directly, you mean constant acceleration, then I would think you could just use the average for 0.0 to 0.5 and 3.5 to 4.5 and then just multiply and add.
Area under the curve, Emily. Which should be two triangles and a rectangle, right? So, (600-100)*(0.5-0)/2 + 600*(3.5-0.5) + (600-100)*(4.5-3.5)/2 = 125+1800+250=2175.

I only have a few minutes until I have to teach a nerd class, so I'm cramming in all the posting I can.
Hi Sophia! You know, I always picture you as you were prom night in Chicago, all gussied up with tiara and your medal.
More math talk, please. This could be mathier.
Feh. I read the wrong answer. Which is good in that I think I calculated the problem correctly, but makes me feel dumb because I was agonizing over it. Mind you, they seem to think it's a problem testing an understanding of integral calculus, whereas I did it with 9th-grade geometry.

So I still gotta say, washing the dog sounds fun.
[silly me, fearing the cereal.]
