Okay, so lets look at the equation.

The Skate accelerates at 2.0m/s². This can confuse some people but basically all you need to do is plug in the seconds.

So lets do 1 second. It would be 2.0m/1² which is 2.0m.

Lets do 2 seconds. It would be 2.0m/2² which is 0.5m.

Lets do 3 seconds. It would be 2.0m/3² which is 0.222m

Lets do 3.5 seconds which is about 0.163m.

Add those together and you get 2.885m.

This may be wrong but this is what I got given what you gave (that its seconds squared).
