Adventuretime:

the graph is show ing you the wave amount hopes this helps

Nicole:

@vocaloid

axie:

I can help! what are you confused about!

axie:

1.Where does the wave start?

Nicole:

the p wave starts at 8:07 ?

axie:

yup

Nicole:

and the s wave starts at 8:09?

axie:

Exactly!

Nicole:

okay so to find the different I would need to subtract both times? which would mean the difference is 2 minutes

anivearb0109:

yes

anivearb0109:

good job

difference is indeed two

Nicole:

Okay and then to find the distance it says you need a graph which is this one:

Nicole:

so we would first go up to 2 on the y axis

Nicole:

but how would we know the distance?

axie:

it goes from 600 to ~1275

Nicole:

Im not sure what you mean can you please clarify

axie:

1275-600=??

axie:

your asnwer is the answer of that equation

Nicole:

but why did you choose 1275 and 600?

axie:

600 and 1275 are two of the points that the line crosses, since it is a constant rate you can use any two of the bolded lines

Nicole:

wouldnt it be 1,200 or 1,300 because thats where it intersects

xxDeppressionxx:

He choose them because they go from 600–1275

And those numbers are what you need to get the Answer.

Im just sitting here watching all this happen

Nicole:

So the y axis shows the minutes..so we go up to 2, then we keep going until we find the point where there is a point to intersect on the line that goes across the graph and you go down to whatever number that is there. am I wrong?

That is correct, i messed up but i thought i corrected myself, i apparently didnt tho, you are correct

axie:

Im sorry, i shouldve caught that faster, i was certain that i fixed it but i didnt

Nicole:

Its okay...Okay so would it be 1200 or 1300 because i cant tell. it kinda intersects at the midpoint of both numbers

It is 1275, its 3/4ths of the the way between teh two

Nicole:

Okay do you mind helping me with 2 more like these?

Nicole:

just so i can make sure Im correct

xxDeppressionxx:

Sure

axie:

@xxdeppressionxx you got this bro, i got my own math to work on XD

Nicole:

okay so I got the first part do you think im correct?

xxDeppressionxx:

yes you are correct, so now you need to find the Epicenter right?

Nicole:

Yes

xxDeppressionxx:

look over your notes that we just did.

xxDeppressionxx:

Tell me what the next step is.

Nicole:

Actually I think it is wrong, because im trying to find the distance on the graph and I am not finding any point that intersects

Nicole:

wait actually no, its been 900 and 1000

Nicole:

between*

Nicole:

so 950?

xxDeppressionxx:

Yup

xxDeppressionxx:

Because that is between 900 and 1000.

xxDeppressionxx:

it would be 950.

Nicole:

okay and this is the last one

Nicole:

what do you think the p wave is?

xxDeppressionxx:

you tell me, but it could be 900

xxDeppressionxx:

what do you think?
