Answer:

A

Explanation:

Morning Rate = 3 pints/4 minutes

Afternoon Rate = 2 pints/3 minutes

Lets find the rate in pints per hour for each. (Remember, 60 minutes in an hour). Let x be number of pints

Morning Rate =
$(3)/(4)=(x)/(60)\\4x=3*60\\4x=180\\x=(180)/(4)\\x=45$

Afternoon Rate =
$(2)/(3)=(x)/(60)\\3x=2*60\\3x=120\\x=(120)/(3)\\x=40$

Morning Rate = 45 pints/hr

Afternoon Rate = 40 pints/hr

The difference is 5 pints/hr

Correct answer A
