Please help. attached question

Will you upload under .pdf file?

ill try

First 30-min range: d lower: 0 d upper: 13 * 30 = 390 m/h

lower estimate cant be 0

In your lecture, time can't be 0?

its asking distance not time

distance = speed * time!

yea but its done in a weird way. its not asking just the lowest interval or the highst interval

Should you upload your notes so I can compare?

I'm researching on net now!

i don't have online notes

but i may be able to show u the book notes

Anything that help me to catch up what level you are is fine :)

thanks! one sec

there will be two files because it all doesnt fit on the screen

:)

this is lower estimate or wahtever

upper

I'm sort of getting the idea :)

okay thanks! I got all of the files attached here

Don't worry, I'll finish up! Just do whatever you want, then I'll show you how to!

thanks

Because Roger's speed is decreasing: Upper estimate distance for the first 30 min: 15min ( 15 + 14 ) = 435 mi Lower estimate distance for the first 30 min: 15 min ( 13 + 14 ) = 405 mi Upper estimate distance for the whole 90 min: 15 min ( 15 + 14 + 13 +13 + 11 + 10) = 1140 mi Lower estimate distance for the whole 90 min: 15 min ( 0 + 10 + 11 + 13 + 13 + 14 ) = 915 mi

Hey, it takes so long, somehow my internet connection so unstable!

thank you! ill try it out

:)

hm it says itis wrong. I

All wrong?

it doesnt say which one or if all is :( but i remember get 1140 my last tim for something

How about switch lower upper!

but that does not make much sense i dont think

I got 1140 for the upper!

After calculation, I see it makes sense, because the speed is decreasing!

i don't know :( i just had to get all new values and this is my last chance.

Are you sure you enter correctly? because in the question, the lower estimate goes first while my answer the upper estimate goes first!

yea i made sure of that

You did answer in right order already?

yes

i got all new values :(

I'm recalculating!

well i have new stuff :(

new numbers

Something wrong with my calculator!

hope not lol

Because the result different!

its okay. I got new numbers anyway

The method is exactly right! All you do make sure the calculation correctly!

ok ill try it again thanks

Do you want to upload, so you can compare your answer!

i just dont think its doen right fo some reason

upper is adding that extra value at the end. whatever it is i think

The idea is estimate from right end or left end!

its not ends. lower is all of them calculated not including last interval and upper is including last interval

Exactly!

Did you see the set of numbers I entered just different at the left or right end!

im confused im sorry but it didnt look like the examples. its okay! thankyou for trying and giving ur time.

In the example, it has total 6 sets!

When they estimate lower/ upper: they calculate 5 sets!

hmm you might be right. I was confused. shouldi show you my new examples or i could just try it soon

Go ahead, I'd like to clarify it to you!

ok one sec

I'll make sure triple check my calculation this time!

ur awesome thanks here it is

Lower estimate distance for the first 30 min: 15 min ( 14 + 15 ) = 435 mi Upper estimate distance for the first 30 min: 15min ( 16 + 15 ) = 465 mi Lower estimate distance for the whole 90 min: 15 min ( 15 +14 +14 + 12 +11) = 990 mi Uppper estimate distance for the whole 90 min: 15 min ( 16 +15 + 14 +14 + 12 + 11) = 1230 mi

are ya confident :)

Yep!

i think the book mislead u. It's not always six boxes, this one is seven boxes. I feel like lower would be 15(16+15+14+14+12+11) and upper would be 15(15+14+14+12+11+0)

i didnt plug in yet becasue this is my last chance.

No matter how many sets, the idea is just enter n -1 sets from left or right!

I know and I already tested my number over and over!

ok ill do it! haha

it was wrong :( its okay i cant do it anymore times. But you were great. I'll give u points

I really don't need point! All I want is helping you out :(

well ur awesome for being so nice. I can't do any more of it

I believe the system malfunction! You can complain about it with your teacher!

well thank you!

My friends have the same problem while taking the online quizzes.

yea it sucks. Thanks so much though ur great.

Talk to him, you'll see!

Good luck!

thanks!
