Mary travelled 70 miles/hour due north. this is an example of what?

velocity.

Explanation:

Velocity is a vector quantity, which consists of:

- a magnitude, which is equal to the ratio between the displacement of an object and the time taken for the displacement to occur:

- a direction, which is equal to the direction of the displacement

In this case, we are given both the magnitude (70 miles/hour) and the direction (north), so this is an example of velocity.
