s on A runner is also on the track going in the same direction as the walker, running at an unknown constant speed. The runner and the walker are together, then meet each other again when the walker has completed 1/2 of a lap, or 200m. What is the runner's speed? A walker is walking at a constant rate of 1 m/s on a circular track that is 400 m in length.

Art and physical endurance enthusiasts compete in an annual race called the Kinetic Sculpture Grand Championship (A kinetic sculpture is a sculpture that is able to move). Let's suppose a kinetic sculpture team races its vehicle on a river. It takes 0.05 hours for the vehicle to race down the river going with a current of 3 miles per hour, and 0.15 hours to travel the same distance back up the river against the current. a. Set up a linear system of equations for this problem where d represents the distance traveled and x represents the rate at which the kinetic sculpture is moving. b. Find the rate at which the kinetic sculpture was moving down the river and back.

While strolling downtown on a Saturday Afternoon, you stumble across an old car show. As you are walking along an alley toward a main street, you glimpse a particularly stylish Alpha Romeo pass by. Tall buildings on either side of the alley obscure your view, so you see the car only as it passes between the buildings. Thinking back to your physics class, you realize that you can calculate the cars acceleration. You estimate the width of the alleyway between the two buildings to be 4 m. The car was in view for 0.5 s. You also heard the engine rev when the car started from a red light, so you know the Alpha Romeo started from rest 2 s before you first saw it. Find the magnitude of its acceleration.
