Problema Solution
There are two machines that produce aluminum cans. The newer machine can produce 2400 cans in 210 minutes. It takes the older machine 280 minutes to produce that many cans. If the two machines work together, how long will it take them to produce 2400 cans?
Answer provided by our tutors
We will use the general equation:
(number of cans produced)=(rate)(time)
2400=((2400/210)+(2400/280))t
t=120 minutes
