Question

water flows out of a tap at the rate of 1.5 gallons per minute at this rate how much water will flow out of the tap in 1/2 hour

Answer 1

1/2 hour equals to 30 minutes.

Now, we know that our unit rate is 1.5 gallons per minute.

So now we need to find out how much per 30 minutes.

We can set up a proportion

1.5/1 = x/30

Cross multiply

1.5* 30 = 1x
x= 1.5*30
x= 45

Final answer: 45 gallons of water will flow in 1/2 hour.

Answer 2

45 because 1.5*30 minutes in a half hour is 45 gallons of water
