After 3 seconds, her car was 40 feet in front of the start line. Write an equation to represent Sam's car. Let x represent the number of seconds and f(x) represent the distance Sam's car is from the starting line. The race is over at 15 seconds. The winner is defined as the person that is furthest from the start line. Who won the race? How do you know?
