第二小題求解 謝謝
非選X素養 走入數學的二維世界 1 如右圖,珍珍與彬彬分別在坐標平面上(100,-87)與(-20,53) 兩點的位置。今兩人同時出發,且珍珍每分鐘向左平移3個單位再 向上平移5個單位;彬彬每分鐘向右平移3個單位再向下平移2個 單位,請回答下列問題: (x-2.1+5) (1)求珍珍與彬彬出發滿10分鐘時的位置坐標。 (2)判斷兩人在移動過程中是否會相遇?如果會,請求出相遇位置的 坐標;如果不會,請說明不會相遇的理由。 (769-33 彬彬 三閱讀素養教育 y (-20,53)] √ (100-87) (7.5)× 10 (100-7.-87+40) = (73-37) -(27.50) 彬:(-0.53) (3-2)×10 (20+30.53-20) =(30-20) (10.33) * O -X 珍珍 (100,-87)
