Question

Part 1 Sam car: When the timer started Sam car was 1 foot In front of the start line His car 13.5 feet per second

Part 2 Alice car: Travels 12 feet per second After 3 seconds Her car Was 40 feet In front of the start line

Let x represent the number of seconds into the race



Let y represent the distance from the start line

Part 1: Write an equation to model Sam's car. 

Part 2: Write an equation to model Alice's car.

3. 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? 

Answer 1

Sam: 13.5x = y

Alice: 12x = y

Insert 15 for the seconds:

Sam: 13.50 * 15 = y ... y = 202.5

Alice: 12 * 15 = y ... y = 180

Sam won.
