Answer:The fourth option
Step-by-step explanation:
Let's turn this into a fraction using the given information we already have.

We want the denominator, or the bottom part of the fraction, to be 1 in order for us to have a unit rate.
This fraction can be simplified if we divide both the numerator and denominator by 3.
Numerator: 18/3 = 6
Denominator: 3/3 = 1
Now we have

Any number divided by 1 is equal to that number.

Thus, your unit rate is 6 miles per hour.
Have an awesome day! :)
