You should be able to solve this

>>right
No, 2/3 of her original speed, not 2/3 times as fast.
So that's 10:20 - 5/2x because she took 1.5 times longer on the way back.

Are we also assuming this all happened on the same day?

11:20

she lives in the park
2/3* 0 = 0

>retards forgetting the 1hr rest

Literally not enough information is the only valid answer.
Also,
Mods?

>1.5x

back to middle school you go

you're assuming that 11:20 is the duration of the whole ordeal, which isn't

All this question made me do is realise just how much algebra I've forgotten.

>but this makes no sense

Murica education attacks again.

I thought it was 3/2 OGGA BOOGAA GOOAAOAOOOOAOAAOOGOGOOAOOAO

Should we assume Haruko-san is a virgin?

Haruko-san a qt, she's a pure angel.

What if it's before midnight?
What if it's before new year?
What if it's a leap year?
What if it's before the birth of Christ (1AD)?

This question is blowing my mind.

Can be absolutely anything. It could take her days to reach the park for all we know.

It wants a formula though.
You can write a formula for this with variables. It get's complicated though.

Then it's 11:20 - 1 - S/(2/3V)

11 + 1/3 - 1 - x * 2/3 = T

So it's:
> t = 10:20 (2/3V) - S
is what your saying?

T=10:20-1.5S/V

Do your own homework.

t = install Gentoo time

>doesn't know the answer

I'm saying that you need to define time in a base format, which is usually seconds.

60 secs = 1 min
60 mins = 1 hr
24 hr = 1 day
etc.

You also needs to use 1AD as the base time to calculate a date or time.
Let To = 10:30am, Ta = start, V = speed in same units of S/second, S = distance, Z = to time in seconds from 1AD to that specific 10:30am (we don't know the date),
As we don't have any info on the date, etc, we must only produce the formula relative to To.
So Ta = To . Z - ((5/3) (V/S) - 3600)

I think I had an aneurysm. This just get's more and more complicated the more I look at it.

time to install gentoo

It's ok, time didn't exist before 1970

I was about to say some computers start time at that date.

No, the time she arrived at the park is literally 11:20 minus the time it took her walking from the park(which is distance to the park divided by her speed, 2/3 of her running speed in this case) minus 1 hour of rest, you're overcomplicating it for no reason.

5/3 would be for the entire time, not for simply reaching the park from home.

All that shit and I misread the question.

>To = 10:30am
Was also meant to be 11:20am

Why does anime always include these math problems?

Bout tree fiddy

this is the stupidest...

this

wtf why the fuck would you even need shit like that ?
i'd understand if you are teaching equations with one unknown but this shit ?

It's just to see if you can write the formula, not provide an answer.

>Haruku-san
Stopped reading right there.
Disgusting weebs must be purged

>2/3
>1.5

american education everyone

t_i + v + 60 + (2/3)v = 680 (minutes past midnight)

t_i = 620 - (5/3)v

You fucking retard. For 2/3 of original speed you need 1.5 more time to cover the same distance.

You can add speed to time nigger
Use fucking units and see the result
Transit time is speed/distance

>Speed
>Not velocity
There cannot be a formula because the direction Ha-rookie ran is not known.

Distance / speed sorry
T initial + Transit time= T@ park
Transit time=distance / speed

T@park + 1 hr=Tdeparture
Tdep +Ttranzit'=Tarr
Ttranzit'=(distance)/2/3(speed)
T arr =11:20

Tdep+dist/speed+1 hr+ dist/2/3speed=11:20
Tdep+d/s+3d/2s=10:20
Tdep+5d/2s=10:20

>it says to write the formula brainlet
Okay
Time arrived at park = Time left park - 1 hour

You didn't specifiy what piece of information needs to be the variable the person using the formula has to give to make it solvable. So you write one of six different formulas used to get the answer.
