Question 1173833
<br>
No doubt you have shown the problem exactly as it was given to you....<br>
But it is impossible to know the intended answer, because the meaning is unclear when the problem says one machine "DOES THE JOB 3 TIMES FASTER THAN" another machine.<br>
Sorry....<br>
To be a good math question, the question must be written with language that makes it absolutely clear what the question is.<br>
It's not your fault that many people who write math problems use imprecise language.<br>
