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,
= 
and of smaller belt is,
= 
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,

t = 
Answer: 11/12
Step-by-step explanation:
7/12 and 1/3 don’t have the same denominator, so you can’t just add them right away. You have to give them the same bottom number. 1/3 = 4/12, so you can do it like this:
7/12 + 4/12 = 11/12
11/12 is in simplest form, so that should be correct! Hope this helps! :)
