<u><em>Answer:</em></u>Each will have passed 17 tests and it will take 3 weeks. 
<u><em>Explanation: </em></u>Let x be the number of weeks. 
The number of tests <u>Travis</u> passes to begin with is 11. 
We then add 2 tests per week, or 2x to that, giving us: 
11+2x. 
The number of tests <u>Jenifer</u> has passed to begin with is 2. 
We then add 5 tests per week, or 5x to that, giving us: 
2+5x. 
<u>Setting these equal, we have: </u>
11+2x=2+5x. 
<u>Subtract 2x from each side: </u>
11+2x-2x=2+5x-2x; 
11=2+3x. 
<u>Subtract 2 from each side: </u>
11-2=2+3x-2; 
9=3x. 
<u>Divide both sides by 3:</u>

3=x. 
It will take <u>3 weeks</u>. 
In 3 weeks,
Travis will have passed: 
11+2*3 = 11+6 = 17 tests. 
Jenifer will have passed the same number, since she catches up with him at this point.</span>
