Question

Running at the same constant rate, 6 identical machines can produce a total of 270 cans per minute. At this rate, how many cans could 10 such machines produce in 4 minutes?

Answer 1

6 machines = 270 cans per minute

Find number of cans 1 machine can produce in 1 min:

6 machines = 270 cans per minute

1 machine = 270 ÷ 6 = 45 cans per minute

Find number of cans 10 machines can produce in 1 min:

1 machine = 45 cans per minute

10 machines = 45 x 10 = 450 cans per minute

Find number of cans 10 machines can produce in 4 min:

1 min  = 450 cans

4 min = 450 x 4 = 1800 cans

Answer: 10 machines can produce 1800 cans in 4 mins
