Question

URGENT

There are two machines that produce aluminum cans. The newer machine can produce 4200 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 4200 cans?
how many minutes?

Answer 1

120 minutes

Explanation:

To solve this problem, you need to find the unit rate of each machine. The newer machine produces 20 cans per minute, while the older machine produces 15 cans per minute. Together, they produce 35 cans per minute. Dividing 4200 by 35, you get that it would take 120 minutes to produce that many cans.
