Question 1103450
<br>
The setup for the problem is straightforward, using the standard algebraic process.  But I suspect the numbers in the problem are wrong, because the answers are irrational numbers.  Worthwhile problems like this have answers that are rational numbers.<br>
Let x be the number of hours it takes company B to do the job; then x+2 is the number of hours company A takes.<br>
Then the fractions of the job that the two companies do in 1 hour are 1/x and 1/(x+2).  And since together the two companies together do 1/27 of the job in 1 hour,<br>
{{{1/x + 1/(x+2) = 1/27}}}<br>
I won't take this any further, because, as I have said, the answers are unreasonable for a problem of this type.
