AMC 10 2020b Problem 13

  • Paper

Andy the Ant lives on a coordinate plane and is currently at (−20,20)(-20, 20) facing east (that is, in the positive xx-direction). Andy moves 11 unit and then turns 90∘90^{\circ} left. From there, Andy moves 22 units (north) and then turns 90∘90^{\circ} left. He then moves 33 units (west) and again turns 90∘90^{\circ} left. Andy continues his progress, increasing his distance each time by 11 unit and always turning left. What is the location of the point at which Andy makes the 20202020th left turn? (A) (−1030,−994)(B) (−1030,−990)(C) (−1026,−994)(D) (−1026,−990)(E) (−1022,−994)\textbf{(A)}\ (-1030, -994) \textbf{(B)}\ (-1030, -990) \textbf{(C)}\ (-1026, -994) \textbf{(D)}\ (-1026, -990) \textbf{(E)}\ (-1022, -994)
