Back to School

Here's my take on the math problem from last post:

1a) Every chair you pass takes 4 seconds. At zero seconds you are across from chair 2, at unload you are across from chair 200. 200 - 2 = 198. 198 * 4secs = 792 seconds, or 13 minutes and 12 seconds.

1b) On chair 35, directly across from chair 200, the chairs in front of you are chairs 34 through 18. Chair 18 is at the unload spot, and chair 17 is directly across. At time zero, you are directly across from chair 200 (or chair zero), at unload you will be across from chair 34. 34 - 0 = 34. 34 * 4secs = 136 seconds, or 2 minutes and 16 seconds.

Today was my first day at my main placement. It was great to be back with the students I got to meet in September, and I received a very warm welcome. We capped off the day with a staff meeting, and I forgot how much those suck. I don't think I would mind them as much if I was actually a teacher and had some say in the matters discussed, but being a student teacher and having to sit through the conferences is torture. There is a teacher who discovered she has cancer in her bone marrow last month. She is currently undergoing chemo treatment and visits the school 18 hrs per week. During the staff meeting she said, "This doesn't make chemo treatments seem that bad!"

Oh! The Dr. is right on 1a, it does seem like I'm asking from when the chair is even with chair 4... that was inadvertently sneaky of me! 784 seconds for 1a!

Okay - so I got 50%. I'm happy with that. I'm a doctor, not a math geek.

My mistake was obviously putting the higher numbered chairs in front of my chair, which is a silly mistake (and quite reminiscent of mistakes I made in high school and college). The foreshadowing was great. I should have guessed I'd get it wrong when I started out by saying, "Question 1b is easier."

I love me some math problems.

As the creator of the problem, I'll have to admit to making the exact same mistake the first time I tried to solve it. It wasn't until I started posting the problem that I realized the chair numbers decrease in front of you instead of increase.
