Jana looked at her wristwatch as her family drove from syracuse to albany. After fifteen minutes, she checked the odometer on the dashboard to see how many miles they have traveled.What was she measuring?
A-Speed
B-Motion
C-Velocity
D-friction
Heres what I can't figure out, it can't be friction, nothing to do with traveled miles.It might be speed due to the fact that if MPH is higher more miles are given.....Not to sure about velocity and motion, i know velocity is the rate of motion but i still don't really get it.
Velocity is a vector quantity; i.e., it has both a speed AND a direction. Here is a site that talks about that.

In this context, Jana is measuring the distance or the amount of miles they have traveled, which is related to speed. Speed is defined as the rate at which an object moves, specifically the distance traveled per unit of time (e.g., miles per hour).
The correct answer is A - Speed.
Motion refers to the act or process of moving, so it is a more general term that can encompass various aspects of movement, including speed. Velocity, on the other hand, is a vector quantity that includes both the speed and the direction of motion. Since the question focuses on measuring distance traveled, speed is the most appropriate answer.
To calculate speed, you would divide the distance traveled by the time it took to cover that distance. In this case, Jana is measuring the distance traveled by checking the odometer, which indicates the number of miles they have covered. By keeping track of the time passed (in this case, after 15 minutes), she can determine the speed at which they are traveling.
