machine manufactures at the rate of 20 cans per hr
In 2 hr machine m/f 40 cans

3 boxes = 30 cans.
There are total 40 cans to be packed

rate of maria = 30 cans per hr.

For 40 cans total time taken by maria = \(\frac{40}{30}\) hr = 80 mins

We just have to calculate Maria's rate of packing one box. That's 20 minutes.
So for 4 boxes in 2 hours (40 cans), it'll take 20*4=80.
