She starts 5/8 around the wheel 5/8 * 2pi is approx 3.9 so t_i = 3.9 Intital GA coords (x,y,t) (138, 52, 3.9) It rolls 50 blocks and r=30 blocks s=rt 50=30*t -> t=1.7 Final GA coords (x,y,t) (187, 7, 5.6) Change in GA coords (x,y,t) (49, -45, 1.7) Initial MC coords (x,y,z) (83, 100, 105) Final MC coords (x,y,z) (132, 55, 105) Wither [Mr Moran] coords (x,y,z) (128, 76, 105) Difference between Rachels final position and Mr. Moran (x,y) (5, -21) distance: d = sqrt(5^2 + (-21)^2) = 22 Change in MC coords (x,y,z) (49, -35, 0) *Note that Minecraft z-coor have been suppressed because it does not change.
