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