Answer 1

Ok, so to tackle this problem you have the speed, the time, and are looking for the distance. v=d/t, if you're familiar. Isolating d on one side, you get d=vt. Let's do just that.
d=3.6*10^-2*1.8*10^4
d=648 mm

There are 2 sig figs for both elements, so there should be 2 sig figs in the answer. (sig figs are significant figures.)
So the answer would be DG.
