Machine manufacturing rate = 20 cans/hour

1 Box = 10 Cans

Maria Packing rate = 3 boxes/hour = 30 cans/hour = (1/2) cans/minute

If the machine ran for 2 hours:

No. of cans manufactured = 20*2 = 40 cans

Time taken by Maria to pack one Can = 2 minutes

Time taken by Maria to pack 40 cans = 40 * 2 = 80 minutes

Therefore the correct answer is C
