Help poor Swat 3 with his Science homework.

[Blockzillahead]

Do you mean v as speed, because if v is velocity we don't know her direction.

Yeah v is speed.

still not right
if she goes 4 miles / hour on the way back she'll get back in 1 hour and her avg speed will be
d=r*t
8=r*3
r=8/3


again there's no solution to this problem because if she wants to average 4 miles an hour on an 8 mile trip she's gonna need to haul more ass on the way there than 2 mph

Yeah I just realized the question makes no sense.

It takes her 2 hours to travel 8 miles at the speed of 4mph
It takes her 2 hours to travel 4 miles  at the speed of 2mph

She will not make it back in time unless she travels at the speed of light.

Yeah I plugged that in and I got like, 3.73427734 or something.

You have to average it. Basically this needs to do a teleport.

Or she gets eaten.

Here I have a table that I am using:

2 mph |  _ mph
4 mi    |  4 mi
2hr      | _ hr

to everyone saying it's not physics

it's talking about velocity and motion
it's physics

now, that's not to say it's COMPLICATED physics, but this is probably in one of those 8th or 7th grade "intro-to-physics" classes

It's talking about speed, not velocity.  There's a difference.

[Swat 3]

It's talking about speed, not velocity.  There's a difference.

no this is pre-whatevr 8th grad physics

you have to know what speed if before you know what velocity is you doink

No point in trying to figure it out, it's not possible. Tell your teacher she done goofed.

[ßlöükfáce]

I answered it for you

[Swat 3]

No point in trying to figure it out, it's not possible. Tell your teacher she done goofed.

i know it isn't possible

but we need an answer, my mom is trying to do it right now and she is goofed.

yeah so maybe she got eaten

I got it
She would need to teleport back to be on time for piano lessons

let me explain
If she needs to go average 4 mph for 8 miles, she has 2 hours
If she only goes 2 MPH on the way over, and its 4 miles each way, it took 2 hours to get to grandma's.
Therefore, by the time she gets there, she is already late.

I answered it for you

Yeah I see so basically it is not possible.

[Operator¹]

your answer is light speed

[SWAT One]

The answer is 6.

[Operator¹]

The answer is 6.

well poop

6 mph

trust me i'm a friend

[ßlöükfáce]

She would need to go at least 240 MPH (4 miles per second) on the way back, to be on on time for piano lessons.

[Swat 3]

Actually yeah my mom said 6 lol.
