Answer:
<em>120 minutes or 2 hours</em>
Step-by-step explanation:
<u>Proportions</u>
The method to solve the problem is to compute how many cans produce each machine per minute, then add them to obtain the total cans produced by both. Finally, we compute the time to produce 4200 cans at that level of production.
The newer machine produces 4200 cans in 210 minutes, it means it produces
![\displaystyle \frac{4200}{210}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B4200%7D%7B210%7D)
=20 cans per minute
The older machine needs 280 minutes to produce the same 4200 cans, to it produces
![\displaystyle \frac{4200}{280}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B4200%7D%7B280%7D)
= 15 cans per minute
Together, they produce 20+15=35 cans per minute. Thus, to produce 4200 cans, they need
![\displaystyle \frac{4200}{35}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B4200%7D%7B35%7D)
= 120 minutes or 2 hours
I do not know the answer to this i suck at math
