Thanks skeeter. That helped, I got the right answer.

I got more questions I do not understand.

Edit: I forgot to specify what I'm actaully stuck on, the 5th question, where the skater is 2 seconds earlier than the cyclist. I'm just wondering how to put it on the graph. So, I assume SKATER:$\displaystyle 160=12*22$, is that right?

A cyclist, passes the starting line $\displaystyle t=0$

The cyclist reaches the finish at $\displaystyle (t=22)$

What I have so far:

1- the distance of the starting from the finish line

$\displaystyle 260m$

correct
2- the distance travelled after the finish line

$\displaystyle 24m$

correct
3- the acceleration of the cyclist

$\displaystyle -3ms^-2$

correct
4- the average speed of the cyclist from the starting to finish

$\displaystyle 10ms^-1$

|v{avg}| = (260 m)/(22 s)
5- A skater passed the starting line 2 seconds before cyclist. Skater is travelling at a constant speed of $\displaystyle 11ms^-1$. Who wins the race and how much?

t = 260/11 = 23.6 s ... but he got a 2 second headstart, so the skater crosses the finish line at t = 21.6 s relative to when the cyclist started.
