So, my formula is:<br /><br />D = 350T + 325(T+1)<br /><br />So, once I have the cross-multiplied distance, substitute that back in for D and solve for T...

Distance (D) equals rate (R) times time (T). We know the rate and we know that the time it took to get there is an hour less than it took to get back. <br /><br />D = 350 * T = 325 * (T+1)<br /><br />We don't need distance, we need time. <br /><br />T = D / 350<br />T +1 = D / 325<br /><br />Ok, here's where I forget my algebra formulas and start to cheat. I found the greatest common divisor for the rate. Both speeds are divisible by 25. <br /><br />350 / 25 = 14<br />325 / 25 = 13<br /><br />There's some kind of algebraic rule that allows you to flip the denominator to find the answer, but I have no clue what the formula is. If you multiply 350 by 13 and 325 by 14 you'll get the same number which would be the distance. So basically I think I can give you the answer, but I can't give you the exact formula for getting there. I'm more the engineer type, I don't give a crap about the theory as long as it works. <br /><br />Hope that helps, don't worry about any prize, I just got a package from you anyway.
