How to find speed, using a distance time graph.
We read off the total distance travelled from the y-axis
We read the total time take and convert this into hours. Remember 2hr and 30 minutes is 2.5hours
We use distance / time

Thanks a million, you help me with my physics homework!
thanks
Versus maximum speed?
Thanks for the help
After being indulged into vector calculus. I have forgotten that scalars exist
There is an interesting aspect in AVG sped per time unit. It is not linear or I don’t know how better to describe it but maybe you can give me explanation for it.
THE AVG speed here for the whole distance is 64km/H.
The AVG speed for the first 1 hour is 70km. For the second hour and half the avg speed is 60km/h. (According to the graph)
So if you take those two AVG and average them, you should get 65km/h, yet you proved it is 64km/h. And this will become more and more pronounced if the difference between those two avg speed is bigger and bigger.
Why the general mathematical average doesn’t equal to the avg per time unit? There must be some law or rule that explains that.
Thankyou. Very helpful Sir.
Tysm helped me a lot 🙂
How do u find the final speed?
so helpful
How do you do it if it’s in meters per second
u suck
Thanku so much sir
Thank u this helped a lot!!! 💙
Tysm i rlly found this helpful!
