1. **Problem Statement:** You start at the pin (starting point), go to point A, then back to the starting point, and finally to point Z. The horizontal line is divided into equal intervals of 10 m. 2. **Step 1: Find the distance from the starting point to point A.** - Since the line is divided into intervals of 10 m, count how many intervals from the starting point to A. - Suppose point A is 3 intervals away, then distance $= 3 \times 10 = 30$ m. 3. **Step 2: Calculate the distance traveled after going to A and back to the starting point.** - Distance to A $= 30$ m. - Distance back to start $= 30$ m. - Total distance traveled $= 30 + 30 = 60$ m. 4. **Step 3: Find the displacement after going to A and back.** - Displacement is the straight line from start to end point. - Since you returned to the starting point, displacement $= 0$ m. 5. **Step 4: Calculate the total distance covered after arriving at point Z.** - Suppose point Z is 5 intervals from the start. - Distance from start to Z $= 5 \times 10 = 50$ m. - Total distance traveled $= 30$ m (to A) + 30 m (back) + 50 m (to Z) $= 110$ m. 6. **Step 5: Find the displacement after arriving at point Z.** - Displacement is the straight line from start to Z. - Since Z is 5 intervals away, displacement $= 50$ m. **Final answers:** 1. Distance from start to A $= 30$ m. 2. Distance traveled after going to A and back $= 60$ m. 3. Displacement after going to A and back $= 0$ m. 4. Total distance covered after arriving at Z $= 110$ m. 5. Displacement after arriving at Z $= 50$ m.
