Question

Please help:

Answer 1

Justin takes the bus home from school. He gets off the bus, walks a short distance to his friend's house, and stops to talk. Then he walks to his house. Sketch a graph for this story that compares distance from home to time. Explain the shape of your graph.

Answer 2

Hello, Tahmina! Do you get this at all or are you lost?

Answer 3

both :)

Answer 4

sorry im confused and lost :)

Answer 5

Hee hee, okay. Let me help you out then.

This question is asking you to map out Justin's journey home, basically. So let me get you started.

Answer 6

okay itll be greatly appreciated :)

Answer 7

Okay, here we are. :)

Answer 8

okay got that part done :)

Answer 9

You want to map out Justin's trip home with relation to time. So lets take a look. He starts out riding the bus:

Answer 10

As time passes as Justin rides the bus, he covers more distance until he gets home. The line is sharp because he's going pretty fast.

Answer 11

But that's only part of it. The question says that he gets off the bus and walks to his friends house, which we can assume is still on his way home. How would you graph that part, using the same line?

Answer 12

Very, very good. Since he stopped to talk at his friends house, his journey home paused for a while, making the graph go constant. How would you graph his walk home? It won't be as fast as his bus ride, so we can assume that his journey will be slower.

Answer 13

i dont know!

Answer 14

It is confusing the way you started. I would pick a number like 10 miles for the distance from home at time =0

then I would show the distance getting smaller as time goes along.

Answer 15

It's okay! Because his journey was slower, the line will still go up. Kind of like this:

Answer 16

and then would it go down ?

Answer 17

And phi is correct. We COULD pick a specific amount of time and distance Justin traveled, but it wasn't specified in the question. The line would not go down, because he reaches his destination. We only want to map his journey, not anything that happens afterward.

Answer 18

so is that it? Nothing else?

Answer 19

That's it! :)

Answer 20

I may have to give this one to phi....

Answer 21

Sketch a graph for this story that compares distance from home to time.

It would be better to show the distance from home gets smaller with time. The teacher may not give you credit if you show him moving away from home.

Answer 22

But he isn't moving away from home!

@phi this is incorrect? If so, please help her understand this.
