Hi guys a question here.

A boy walks 100m in 40 seconds. He then runs back to his starting point in 12 seconds. He rests for 10 seconds. He then walks the 100m in 50 seconds and runs back in 13 seconds.

a) Plot a distance-time graph

b) Plot a displacement-time graph

So I might sound dumb here but wouldn't the two graphs look the same?? I'm not sure whether the graph is asking for pure "distance" or whether it's asking for distance from starting point. Help would be appreciated :)

nope! It would look completely different.
Distance does not care about direction.
So all distance travelled (or not travelled) counts.
Displacement is the "distance" from the starting point in this instance (basically).

Also hi! A fellow 2018er =D

Hi! Were you also wanting to know what the graphs would look like?

Excuse the potato quality, and the bad handwriting.
(My graphs are not very accurate, or detailed, at midnight)
