Question

A machine pumps 2.1 gallons of water every 1.6 minutes. How many gallons is pumped per minutes?

Answer 1

Answer:

1.3125 gallons

Step-by-step explanation:

Using the given information, we can set up a proportion;

$\frac{2.1gallons}{1.6minutes} = \frac{xgallons}{1minute}$

Now, we can cross multiply to solve for x.

2.1 = 1.6x
x = 1.3125 gallons

Answer 2

Answer:  1.3125 gallons

Step-by-step explanation: The machine pumps 2.1 gallons of water every 1.6 minutes. 1.6 minutes is 1.6x more than 1 minute. So, we have to divide 1.6 by 1.6. Next, we have to divide 2.1 by 1.6. We can make this a bit easier by multiplying both of them by 10 to get 21/16 which is 1.3125.
