View Full Version : Average Speed Anyone?

I have a lab report due tomorrow but I can't figure out the mathematics of it.

Here's my problem:

I have a data chart showing distance and time, and I need to find the average speed.

There are 31 pieces(?) of data.
Each one has a measurement of distance and its time.
I need to find the average speed of alll these and I can't seem to do it.
My problem is that the distances are measured in cm,
But the time is measured in 1/60th of a second each.

If the time stays consistent... meaning that there's a 1/60th of a second increase each time, but the distance increases each time, HOW DO I FIND THE AVERAGE SPEED?

Thanks.
Peace. :cool:

Unless you explain fully, all I can say is

Average speed = total distance covered/total time elapsed

You have distance (s) and time (t)
The integral of ds/dt is speed.
Average speed is 1/(t2-t1)*integral ds/dt from t1 to t2
So integrate by parts and divide by the time.

I already answered your question here: https://www.askmehelpdesk.com/math-sciences/average-speeed-man-156364.html but I agree with terryg752.
I'm not really sure what KISS is thinking, certainly not keeping with their name ;)

* Man - I think I read too much into the problem. Let me crawl under a rock for a while.
