Answer:
A
Step-by-step 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 = [tex]\frac{3}{4}=\frac{x}{60}\\4x=3*60\\4x=180\\x=\frac{180}{4}\\x=45[/tex]
Afternoon Rate = [tex]\frac{2}{3}=\frac{x}{60}\\3x=2*60\\3x=120\\x=\frac{120}{3}\\x=40[/tex]
Morning Rate = 45 pints/hr
Afternoon Rate = 40 pints/hr
The difference is 5 pints/hr
