Alright so I'm doing this assignment and it is asking (Simon is riding a bike at 12km/h away from his friend Keesha, who is still standing on a sidewalk. How fast would Keesha say the ball is traveling? 5km/h
7km/h
12km/h
17km/h

I would've put 17km/h if it was that simon was moving towards Keesha but it says he's moving away so it would only make sense to subtract 12 from 5 but then that also makes no sense so now I'm just confused.
