(Actually we should call it 'speed', since the graph conveys no information about the direction of the motion, only the speed. Similarly, the distance we'll find won't tell you how far from the starting point you wound up, only how much road or track you covered.)
On the graph, there is some straight or wavy line representing your speed at every instant.
-- Pick the starting time and ending time of the interval you're interested in. Draw vertical lines on the graph at the starting and ending times, long enough to cut the wavy line that represents the speed function.
-- From the value of the function at the start-time, (the point where the 'start' vertical line cuts the graph of the function), draw a horizontal line, all the way across, to the 'end' vertical line.
-- Now you must measure the area of the space bounded by the speed graph and the three straight lines you have drawn. This is easier if the graph was drawn on paper that is marked off in a grid of small squares.
There may be places where the function is below the horizontal line, as well as places where the function is above it. If so, list the area of the space where the function is below the horizontal line as a negative number.
-- When you're done, add up all the positive and negative pieces of area you have measured. The result is the total distance that the moving object traveled during the time between the 'start' and 'end' lines.

im gessing yes
You can tell velocity with a time graph because velocity needs time to tell velocity.
Yes because it is speed/distance=velocity
You can tell velocity with a time graph because velocity needs time to tell velocity. I copied Collin.
yes because speed can be showed on a graph.
Yes because velocity and time are need to tell eachother.
Yes you could use a distance and time graph to show velocity. You could because velocity is distance and time.
Yes because you use time to tell velocity.
Yes you can tell velocity with a time graph.
yes you can use a distance time graph to show velocity because you need distance to equal velocity.
Yes, because you need distance to equal velocity.
yes you can use a a distance time graph to show velocity because velocity is time and distance.
speed/direction the answer is no
No because there is no direction.
yes, because you can use a time graph.
yes you use time to see velocity
**distance time graph
no, no direction(:
I don't know what a distance time graph is so i'm going to guess and say no.
Yes because velocity and time are need to tell each other.
yup
no because it's missing direction. You cannot get velocity without it because the only way to get velocity with speed and distance.
Could you use a distance time graph to show velocity? Why or why not?
No. You could not use a distance time graph to show velocity because velocity is speed/direction.
NO because distance is not velocity, velocity is speed and direction.
No becuase you can not use distance time graph
No you couldn't use a distance time graph to show velocity because velocity is speed/direction. :)
no i dont know
No you can't use a distance time graph to velocity.

Velocity is speed and direction but you have to have distance to go

and you cant use it because velocity is speed not distance and its direction
COPY AND PASTER
no you cant use a graph
YOU COPIED AND PASTEDED
yes u can
you cant use a graph
You cant use a graph because direction would not be shown.
Yes, you can.
no you cant use a time graph

LOOK WHAT I FOUND ON WIKI ANSWERS!
Yes because there are algorithms for figuring out speed with distance and time.
Yes because if you know the distance and time (which the graph would show) you would be able to get the velocity.
No because it needs the direction.
no because the direction.
Liz
No because velocity is speed and direction
No, velocity has to show direction.
