a smoothie recipe uses 5 oranges for every 12 servings.
how many servings can be made with 20 oranges?

○ 48
○ 44
○ 36
○ 60

Explanation:

First Question (Pump Flow Rate)

Step1: Convert minutes to hours

There are 60 minutes in an hour, so the pump moves \( 4 \, \text{gal/min} \times 60 \, \text{min/hr} = 240 \, \text{gal/hr} \).

Step2: Convert gallons to liters

Using the conversion factor \( 1 \, \text{gal} = 3.785 \, \text{L} \), we get \( 240 \, \text{gal/hr} \times 3.785 \, \text{L/gal} = 908.4 \, \text{L/hr} \).

Step1: Find the ratio of oranges to servings

The ratio is \( \frac{12 \, \text{servings}}{5 \, \text{oranges}} \).

Step2: Calculate servings for 20 oranges

Multiply the number of oranges (20) by the ratio: \( 20 \, \text{oranges} \times \frac{12 \, \text{servings}}{5 \, \text{oranges}} = 48 \, \text{servings} \).

Answer:

908.4
