the graph is velocity against time

you need to use it to draw a graph (or equation) of distance against time …

then you can answer the questions

how do I do that? :)

you have a graph of velocity against time

your lectures must have told you some information you can get from it

I don't know how to change velocity to distance

That is hard to believe. We do not do your work for you here. You need to show some effort, or this thread will likely be deleted.

Sorry I'm 13 and my teacher hasn't shown me how?

has your teacher told you anything about the area under a graph?
