How fast can Ron cycle?

[Nate]

Then i go with my original answer of False.  Their speeds aren't constant.

Well I started with rt=D
So r_D*t = (r_R*t) + 25
t = 1 so I get r_D = r_R + 25

75 = r_R(t_D + 3/2)

r_D*t_D = 75
Subsititute this up there...

75 = r_R(75/r_D + 3/2)
Then we plug in r_D that we found in the beginning...
75 = r_R(75/(r_R + 25) + 3/2)
Solving... 0 = 3r_R² + 225r_R - 75

I'm not doing something right... so I tried r=t/d but then that just got me something stupid too x_x

what is all this gibberish

It's called math.  You're making a pretty lousy first impression here -- reminds me of the classic quote, "It's better foor one to be silent and thought a fool than to open one's mouth and remove all doubt"

Ron is going 25mph?
Edit: If only this were in the homework board, I would've seen it earlier.

Yea, how'd you get it? (I still didn't get it ).

This is probably my third or fourth post crushing him. /signed.

Here's a few tips since this is probably your first forum ever:

1. Don't post about stuff you don't know.
2. Don't post something like; "yeah", "no", or " no that's not right ( without an explanation why. )
3. Don't post stuff like " what is all this gibberish? "
