It’s the difference of distances apart over time. Aka how fast bf is moving away from gf, aka what the question is asking for.
Yes, if you want to be pedantic, velocity a vector with direction, so I guess you’d have to frame the question relative to either the boyfriend or girlfriend, but I don’t think the difference between speed and velocity is part of the question.
Speed is just the magnitude of velocity.
My point is that OC was completely missing the mark by not properly accounting for time.
Hi, I made this in 5 mins because I was bored, but it’s late and I’m tired, so could you please explain what I would have to fix in my comment?
My mistake, I didn’t check his math. I thought he was saying if you take distance apart at t(n) and subtract distance apart at t(n-1) you will get distance/sec.
