Question

how to find the average speed from this distance time-graph

Answer 1

I have added the graph

Answer 2

No added graph. :/

Answer 3

There you go sorry about that

Answer 4

No problem. :)

Okay, so in this graph [which is pretty non-uniform]
you just have to find the total distance covered and the total time taken to cover the distance, because, as you may be knowing,\[Average ~~Speed = \frac{Total~~ Distance~~ covered}{Total ~~Time~~ taken~~ to~~ cover~~ that~~ distance}\]

Now from the graph you may approximate saying that the distance covered is
91 meters. And the time taken to cover that is 0.8 seconds.

So the Average speed = 91/0.8

Understood? :)

btw, are the values given there? Because, approximation seems very crude, I am on my Mac and maybe that's why I am not being able to see them . :/

Answer 5

Yes they are given, but nevermind so does that mean that it equals 113.75mm/s

Answer 6

Is it given as 91.2?
If yea, then the accurate answer is 114!! :D

Yeah, you got it! (y)

Answer 7

Thank you so much! I really appreciate it
