Answer 1

Answer: instantaneous speed.

Speed describes an objects distance and the time it takes to get there.

Speed =
`(Distance)/(Time)`

Instantaneous speed describes an objects speed in that very moment. Much like the radar guns that police use to calculate a person's speed on a road.

Velocity describes the speed and direction of an object.

Ex. "That car is travelling 40 miles per hour North."

Answer 2

It could measure the person's speed or also known as velocity. The object could be similar to a police officer using a radar gun to measure someone's MPH/speed.
