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(b^2+g^2):

t0 = 0 t1 = 1.554m
s1 = (1.554m-0m)/1s = 1.554m/s t2 = 3.108m
s2=(3.108m-1.554m)= 1.554m/s

As 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.

Feeling 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.

It’s almost like things aren’t black and white.

Canada is officially a metric using country. Metric is everywhere. That doesn’t mean we can’t use imperial for anything.

You clearly don’t live in Canada. Imperial units are very common for measurements. You ask nearly anyone, old or young, their height or weight, you’re getting an answer in feet/inches or pounds respectively.

Tons of baking is done using cups, tsp, tbsp etc.

Golfers use yards.

I’m sure there are more examples I am forgetting, but you get the idea. It’s not just people who grew up before 1985. It’s everyone.

I guarantee a large portion of the people upvoting you fantasize about this happening, so they can come back with their “witty” remark.

I’ve seen this exact thing all over here/reddit and trust me, it’s rarely a joke.
