I've just completed this question but don't have a mark scheme for it, if anyone has time could you take a look and see if I've done it correctly.

Actually, the last part might be. Looks like youve calculated the 4 end intervals, rather than the 2 center intervals? You want it to be less than 0.1 from 0 (the center).

I thought that was what i had done, by modelling the displacement as sin(wt), i found the time taken for the particle to move from a displacement of 0 to a displacement of 0.1. And then multiplied by 4 because it would cross this region 4 times in an oscillations
