If the thingie traveled at a constant 40m/s for four seconds, it went 40m.
So it WAS 4 seconds! v = at, not at^2. At least that makes sense.
y=y0+v0t+0.5*a*t^2
Where did the 0.5 come from?

What's the chances of her daughter not being totally screwed up?
Frankly, despite custody battles I think better than if ANS were still alive. I just hope there's an affectionate aunt or nanny in there to counterbalance the Daddy's Little Trust Fund effect.

Sir, it's not an offence to let your cat eat your bacon. Okay? And we don't arrest cats, I'm very sorry.
Not really paying attention to the problem as a whole--but in it is there a reason travelling 40m/s for 4s doesn't take you 160m?
You're right.
But somehow I got the right answer. I sorta did it graphically in my head. Now I'm trying to figure out how to explain what I did....

Where did the 0.5 come from?
The integral of the velocity.

Where did the 0.5 come from?
When you do an integral of x^n, it is equal to a constant plus (1/(n+1))*x^(n+1).
[Take this and try to find its derivative - the opposite action to integral - and it's x^n]
So if we have v, the result of the integral is (1/(1+1))*x^(1+1)=0.5*x^2.

Life moves pretty fast. You don't stop and look around once in a while, you could miss it.
Look at all of you with your lovely math brains.

I used to know how to do that stuff. Retained it just long enough to pass a test and then it all went buh-bye. Use it or lose it, peeps.

Right right! Now I remember. Sorta. Oh, calculus. I liked you when you made teddy bears.

Well not canonically, no, but this is transformative fiction.
I know that 4x40 is 160, and that's enough for me.
I do miss my brains, but there's no point crying over spilt neurons.

That's so not the big problem with the sentence.
Oh, I see what you mean. I don't think those periods are necessary either.
