In miles.

Step-by-step explanation:

In the car´s odometer, the measures are in miles, also distances at the road are measured on miles, what makes it the best way to report the distance driven.

However, this also depends on the place where the car is driven, in the USA we use miles, in Mexico, for example, the distances are measure on kilometer, in which case the mile has to be multiplied per 1.60 that is what a mile values on kilometers.

Many cars also getthe count of the total of miles driven, in which case what the driver has to do is subtract the total of miles at the end minus the miles that the car´s odometer had at the beggining of the journey.
