1. **Problem 1: Brittney's run around the track** Brittney runs 400 m around a track and ends up at the starting point. - Distance is the total length traveled. - Displacement is the straight-line distance from start to end point, including direction. 2. **Calculate distance and displacement for Brittney:** - Distance = 400 m (since she ran one full lap) - Displacement = 0 m (because she ended where she started) 3. **Problem 2: Anthony's walk to the pizza place** Anthony walks 4 km east, then 1 km west. - Distance is total ground covered. - Displacement is net change in position. 4. **Calculate distance and displacement for Anthony:** - Distance = 4 km + 1 km = 5 km - Displacement = $4 - 1 = 3$ km east **Final answers:** - Brittney: distance = 400 m, displacement = 0 m - Anthony: distance = 5 km, displacement = 3 km east
