## anonymous one year ago Link to my problem it's the 3rd page number 20. Reasoning!:) thanks! http://www.miamiartscharter.net/ourpages/auto/2012/12/11/50556382/Alg%20I%20Section%204%20Problems.pdf Question- the graph at the right shows the vertical distance traveled as person A walks up a set of stairs and person B walks up on an escalator next to the stairs.!copy the graph. then draw a line that could represent the vertical distance traveled as Person C rides the escalator standing still. explain your reasoning

do you have anything so far @Vanessa123270 ?

3. anonymous

I keep getting confused @jim_thompson5910

4. jim_thompson5910

so you weren't able to get started?

5. anonymous

^^ I drew out the graph but it doesn't make sense @jim_thompson5910

6. jim_thompson5910

can you describe what you drew?

7. anonymous

I drew what it told me. I drew and copied the graph and drew out the lines. I also put distance and time on it and idk what to do next😖 @jim_thompson5910

8. jim_thompson5910

which person is on the escalator other than person C?

9. anonymous

I haven't wrote any info yet😖 could you plz kinda help me out? Haha

10. jim_thompson5910

it's given in the problem

11. anonymous

What do you mean?

12. jim_thompson5910

which person is on the escalator other than person C? it's given in the problem

13. jim_thompson5910

is it person A? or person B?

14. anonymous

B?

15. jim_thompson5910

hopefully that's not a guess do you see how they say it in the instructions?

16. anonymous

Ohh okay yeah I see it

17. jim_thompson5910

what do you notice about the lines A and B?

18. anonymous

Well line A is longer and B is shorter. B is pointing a bit up

19. jim_thompson5910

20. anonymous

Their slopes are like straight and some curved

21. jim_thompson5910

which is the steeper line

22. anonymous

Steeper line would be line A

23. jim_thompson5910

you sure?

24. jim_thompson5910

think of a hill or mountain

25. anonymous

Oh okay then line B

26. jim_thompson5910

do you see how B is steeper? how if you tried to walk up it, it would be harder to climb compared to line A?

27. anonymous

It would be hard to climb because an is steeper

28. anonymous

Because B is steeper

29. jim_thompson5910

yeah think of it like a ramp

30. jim_thompson5910

steeper line = larger slope

31. anonymous

Oh okay now that makes a bit more sense

32. jim_thompson5910

since B is steeper, it has a larger slope, which basically means B is moving faster than A

33. jim_thompson5910

B covers more distance in a shorter amount of time

34. anonymous

Oh okay! Makes sense

35. anonymous

Thank you so much!!:)

36. jim_thompson5910

B is going faster because B is walking up the escalator so would C go faster than B? or slower than B? and why?

37. anonymous

Faster because the lines are Steep

38. jim_thompson5910

is C on the stairs? or on the escalator?

39. anonymous

Escalator

40. jim_thompson5910

is C walking or standing still?

41. anonymous

Standing still

42. jim_thompson5910

so C will be moving slower than B but faster than A this is assuming that the escalator is moving relatively fast and A is walking up the stairs slowly

43. jim_thompson5910

44. jim_thompson5910

|dw:1442286577016:dw|

45. jim_thompson5910

so we'd expect C to be somewhere in the middle in terms of slope can you draw for me what line C could look like?

46. anonymous

C would be in the middle but longer and steeper

47. jim_thompson5910

click on the pencil of my drawing you'll be able to draw on it

48. anonymous

Oh okay! Cool

49. anonymous

Wait I don't see a pencil sorry I'm new to this website

50. jim_thompson5910

on the drawing I did

51. jim_thompson5910

do you see a pencil in the upper right corner?

52. anonymous

I don't

53. jim_thompson5910

you should see this (see attached image)

54. anonymous

Oh okay well it won't let me click on the pencil

55. jim_thompson5910

are you on mobile or tablet?

56. anonymous

Mobile

57. jim_thompson5910

that might explain it I'm on a desktop

58. jim_thompson5910

anyways, C would be any line that is in between A and B, like this |dw:1442287136060:dw|

59. anonymous

Oh okay I got it

60. jim_thompson5910

C is steeper than A, which means C is faster than A (because C is on an escalator and A is on the stairs) B is steeper than C, so B is faster than C (because B is walking while C is still)

61. anonymous

Oh okay thank u so much!!
