Question

check my work plz

Which graph most likely describes the distance a person walks in a 24-hour period?


• Graph IV
• Graph II
• Graph I
• Graph III
My answer is C

Answer 1

Did the problem state what the axes are supposed to represent?

Answer 2

its hard without knowing any other information

Answer 3

You can usually *assume* that the x axis represents Time and the y axis represents the other quantity (Distance, in this case). But they really should label the axes because otherwise it's ambiguous.

Answer 4

^

Answer 5

actually... its D

Answer 6

if youre increasing your distance with hours, itd be an increasing altitude soo.. yea

Answer 7

bc the longer you walk, the further you go

Answer 8

Thanks

Answer 9

"Altitude" is height above sea level. :) I think distance in this case means how far you've walked.

x = time
y = total (cumulative) distance walked

In that Graph IV would make the most sense. You start the day having covered no distance, and as the day goes on, you cover more and more distance. The other graphs don't make sense, because "decreasing cumulative distance" doesn't make sense! How can you "Un-take a step"?

BUT

If

x = time
y = distance from your home (0 = at home, the higher you go the farther away from home you are)

Then graph II would make the most sense. This is because you start the day at home, go away from home, maybe come back for lunch, and go away to practice or whatever, and end the day back at home.

This is why labeling axes is important! :-p
