<h2>4gallons per minute</h2>
Step-by-step explanation:
Step one:
the unit rate is the amount of water per unit of time
Given data
4/5 gallon to decimal= 0.8gallon
1/5 minute decimal= 0.2 minute
We are told that 0.8 gallons run in 0.2 minute
then x gallon will run in 1 minute
cross muliply we have
x=0.8/0.2
x=4
this means that in one minutes 4gallons will run in the faucet
The unit rate is 4gallons per minute
