To convert the given ratio into a unit rate, we need to find out how long it took Carla to run one mile.
To find this, we divide the total time it took her (36 minutes) by the number of miles she ran (4 miles).
So, it took Carla 36/4 = <<36/4=9>>9 minutes to run one mile.
Therefore, the unit rate is 9 minutes per mile.
