Answer:

A. 64 miles per hour

Step-by-step explanation:

In a linear equation, the "unit rate" is generally the coefficient of the variable. The units of the unit rate depend on the definition of the relationship.

Here, the time t is in hours, so the "unit rate" will be <something> per hour. The answer choices suggest that the <something> is "miles". That is, the units of the equation are ...

(miles/hour) × (hours) = miles

With numbers/variables, that is ...

(64 miles/hour) × (t hours) = 384 miles

The unit rate is 64 miles per hour.
