Question

Determine the unit rate for the following problems : he pumped 54 gallons in 12 minutes

Answer 1

they answer is 4.5 gallons per minute ask more

Answer 2

To find the unit rate, we are essentially going to reduce this ratio down to it's lowest possible terms. So in this case, we are going to find how many gallons are pumped every 1 minute.

To do this, we are going to divide 54 by 12:

$\frac{54gallons}{12min}= \frac{4\frac{1}{2}gallons}{min}$

So now that we have this in such terms, we can call it a unit rate. Therefore, the unit rate is 4.5 gallons/min.
