Problem One:
Melanie can paint a certain barn by herself in x days. Her helper Melissa can paint the same barn by herself in 2x days. Write a rational expression for the fraction of the barn that they complete in one day by working together. Evaluate the expression for x =5.
*Slightly modified to prevent cheaters from cheating*
Problem two:
At a well known university, 1/4 of the undergraduate students commute and 1/3 of the graduate student commute. One-tenth of the undergraduate student drive more than 40 miles daily and 1/6 graduate students drive more than 40 miles daily. If there are twice as many undergraduate students as there are graduate students then what fraction of the commuters drive more than 40 miles daily.
Can you solve these problems? [Without cheating from Math.com] If so you'll be entered in a quick BYOND membership drawing.

Nay, I suck at math.

and 1/3 of the graduate student commute. and 1/3 of the graduate students commute.

What tank?
| |
Gas Tank.
| |
At a glance, ...
1) (1/x + 1/2x), (3/10) in 5 days 2) You'll have to explain what you mean by "what is the number of minutes it takes to empty the tank" because I don't drive a car, but it's (2/4 + 1/3) / (2/10 + 1/6) | |
A little more specific? What gas tank? Each of the students tank? Some magical tank? The question talks about everything but how many miles it takes to empty a "tank" with that little information it's an impossible question.

That was part of another problem that I copied and paste sorry for that misconception

The problems should probably be replaced every time they're solved, btw. Unless I got something wrong.
