Physics I

I have this vector that is confusing me I know what I need to do but the components of these vectors are confusing me.
Problem:
You are standing at point with coor dinates (1m, -1m, -2m) another erson is at r(t)=(8m)i - (3m/s^3) t^3 j + (4m/s^2) t^2 k Find distance between you and other person at t=1s.

How do I deal with those m and m/s^3 in the components

Thanks

  1. find position at t=1 of the other person.

    Then, distance=sqrt((x-xo)^2 + (y-y0)^2 + (z-zo)^2 )
