## Thats-me 3 years ago Ok, a little help with this speed measurement...In a minute I'll put a graph up

1. Thats-me

Ok this is the graph, how fast is the car going from A-B and how fast is the car going from B-C?

2. amistre64

do you know a formula for speed?

3. Thats-me

Speed =Distance / time?

4. johnsonshelby

distance = rate x time

5. amistre64

correct

6. amistre64

and i cant see any specific value on the graph

7. johnsonshelby

Are you supposed to answer in variable terms?

8. Thats-me

I know, thats the problem Im having... and maybe variables?

9. amistre64

the distance covered from B to C is what? ignore the time part, how much does the distance change?

10. Thats-me

Ummmm.....

12. Thats-me

Well If I was to put up markers, about 2/3 as much as A-B... I really am uninformed in this topic...

13. amistre64

the orientation of the chart might be confusing |dw:1351868677072:dw|

14. amistre64

how fast do you have to be going to not move?

15. Thats-me

Not very lol, 0mph?

16. amistre64

:) so at least from B to C, the speed is zero

17. Thats-me

But in A-B your distance variable is going up right?

18. amistre64

correct, you are changing your distance from A to B by constant rate, and if we were able to have some points of reference we would be able to determine the speed by finding the slope of the line from A to B

19. amistre64

are the point values for A and B given in a different part of the problem set?

20. Thats-me

Uh no, that graph is the only information ive been given

21. Thats-me

Other than the problems I typed

22. amistre64

then the only thing we can really deduce is that the speed from A to B is greater than zero :)

23. Thats-me

Alrighty then=) ">0" will have to do=)

24. Thats-me

Thanks for your help again amistre=) should be my last question for the day lol

25. amistre64

youre welcome ;)
