Answer:
It will take 3.214 minutes.
Step-by-step explanation:
<em>It is given that, the conveyor belt transports 300 cans in 5 mins and the smaller belt transports 300 cans in 9 minutes.</em>
Thus , the speed of conveyor belt is,
= ![\frac{300}{5} = 60 cans per minute](https://tex.z-dn.net/?f=%5Cfrac%7B300%7D%7B5%7D%20%3D%2060%20cans%20per%20minute)
and of smaller belt is,
= ![\frac{300}{9} = \frac{100}{3} cans per minute](https://tex.z-dn.net/?f=%5Cfrac%7B300%7D%7B9%7D%20%3D%20%5Cfrac%7B100%7D%7B3%7D%20cans%20per%20minute)
Thus, when both are used together,
<em>conveyor belt will transport (60)(t) cans and smaller belt will transport
(t) cans per minute.</em>
Thus the equation becomes,
![300 = (60)(t) + (\frac{100}{3})(t) = (\frac{280}{3})(t)](https://tex.z-dn.net/?f=300%20%3D%20%2860%29%28t%29%20%2B%20%28%5Cfrac%7B100%7D%7B3%7D%29%28t%29%20%3D%20%28%5Cfrac%7B280%7D%7B3%7D%29%28t%29)
t = ![\frac{(300)(3)}{280} = \frac{45}{14} = 3.214 minutes](https://tex.z-dn.net/?f=%5Cfrac%7B%28300%29%283%29%7D%7B280%7D%20%3D%20%5Cfrac%7B45%7D%7B14%7D%20%3D%203.214%20minutes)
