Square Track

Ziron and Zane are running around a square track at constant speeds. Ziron runs at a speed of 2 meters per second, while Zane runs twice as fast as Ziron. They begin at the same point and start running in opposite directions. If they meet after exactly 8 seconds, what is the area enclosed by the square track?

Lucien randomly picks two distinct numbers at the same time from the following group of numbers: $\frac{1}{8}, \frac{1}{4},\frac{1}{2},1,2,4,8$. If the product of the 2 numbers is also a member of this group, how many selections can be done?

k I cannot into nationals, what should I do?
AMathCountsguy10   97
N Mar 9, 2025 by Shaarav14
I am an eighth grader in North Carolina and I am sort of pressured to make nats this year, I only got 26 on last year's state test (orz to @mathprodigy2011) and I have mocked 39, 40, and 37 on the 2014, 2015, and 2022 tests respectively. I am aiming for a 40 this year because that seems to be the cutoff. How should I sufficiently improve? My test is on March 14th, 2025.

To be more clear, last year I got 16/10 and on the tests I have mocked, I got 27/12, 26/14, and 25/12.

one very specific bit of advice i have is to make sure you know how your calculator works

i had practiced with a diff calculator for all my practice/mock tests, so when i walked into target round with my brand new fancy calculator, i sillied 2 problems while having correct expressions that i just had to plug into my calculator, and missed nats by 3 pts
