ELABORATION: Velocity Atroffic sofety engineer was studying travel patterns along a highway. She set up a camera and recorded the speed and direction of cars and trucks that passed. Positions to the east of the camera are positive, and to the west are negative. west east -100 0 +100 Vehicles that are traveling toward the east have a positive velocity, and vehicles that ore traveling toward the west have a negative velocity. 1. Complete the table with the position of each vehicle if the vehicle is traveling at a constant speed for the indicated time period. Then write an equation. velocity (meters per second) time after passing the ending position (meters) equation describing position camera (seconds) +25 +10 +250 25 10 = 250 -20 +30
