Question

In the morning a farmer packed 3 pints every 4min. In the afternoon she packed2 pints every 3min. What is the difference between her morning and afternoon packing rates, in pints per hour?

Answer 1

1 hour = 60 minutes

morning: 60 minutes / 4 = 15

15*3 = 45 pints per hour

afternoon:

60 / 3 = 20

20* 2 = 40 pints per hour

45-40 = 5 pints per hour difference
