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

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!
