A traffic safety 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 by the camera. Positions to the
east of the camera are positive, and to the west are negative.
Vehicles that are traveling towards the east have a positive velocity, and vehicles that are
traveling toward the west have a negative velocity.
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.
