I’m talking about my previous response. I already said their answer is wrong.

Well that’s my point. The answer is correct in this specific case, because it’s already “built-in” so to speak.
You want to figure out distance per second. One way to do this is calculate distance apart at t=0,1,2…
The difference between each point would be the average speed over that second.
Using sqrt(b2+g2):
t0 = 0 t1 = 1.554m
s1 = (1.554m-0m)/1s = 1.554m/s t2 = 3.108m
s2=(3.108m-1.554m)= 1.554m/sAs you continue this you will see they travel at a constant speed apart from each other. The reason this is working is because you need to divide distance by time. Dividing by 1 second won’t change the value of the number after you subtract. If you notice you can do (t2-t0)/2s and also get the same answer.
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.
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.
ji17br@lemmy.mlto You Should Know@lemmy.world•YSK to lose weight, fill up with foods low in caloric density and high in fiber, like fruits and vegetables. This can trigger satiety without the overload of calories and beats going hungry long term.113·11 months agoFeeling full is about volume of food. With high calorie dense foods like fast food, that’s going to be a ton of calories. With low calorie dense foods you can eat the same amount of food, and eat substantially less calories.
The only thing that matters in weight loss is calories in, calories out.
I get that it’s harder for some people, but finding less calorie dense foods that you enjoy will go a long way towards helping lose weight. Also, don’t drink pop unless it’s diet.
