Which quantity best describes this description? Justin walks at 3 miles per hour north, and then speeds up to 4 miles per hour.

(This is a question from IPC,)

I just wanted to check with Brainly.

The answers are:

A. Acceleration
B. Velocity
C. Inertia
D. Speed

I went with Acceleration, but it could also be velocity, since it's walking in a certain kind of direction.

I wanted to know if anyone else had thoughts, or if I should change my answer to B?

Personally, I agree with your answer, namely that the likely-intended event happening here is one of acceleration. Having said that, I also want to add: it pains me to see this type of wording because, clearly, it is vague and only invites confusion of the type you are talking about.

Good luck!
