Start at 36, divide by 3 (.00176)
  4. 4. Time/Distance Relationships <ul><li>Mr. Bress’s two nephews are having a race. Because he is older, Joseph gives Ari a 5m head start. Joseph runs at a speed of 7.7 mps, and Ari runs at a speed of 6.5 mps. The race is 50 meters. </li></ul><ul><li>Write an equation to find out how long it will take Joseph to finish the race. </li></ul><ul><li>Write an equation to find out how long it will take Ari to finish the race. </li></ul><ul><li>Determine who will win the race, and determine how far ahead the winner was when he crossed the finish line. </li></ul>
  5. 5. Time/Distance Relationships <ul><li>Mr. Bress’s two nephews are having a race. Because he is older, Joseph give Ari a 5m head start. Joseph runs at a speed of 7.7 mps, and Ari runs at a speed of 6.5 mps. The race is 50 meters. </li></ul><ul><li>Write an equation to find out how long it will take Joseph to finish the race. </li></ul><ul><li>Write an equation to find out how long it will take Ari to finish the race. </li></ul><ul><li>Determine who will win the race, and determine how far ahead the winner was when he crossed the finish line. </li></ul>Write an equation to find out how long it will take Joseph to finish the race. y = 7.7x (when y = 50) Write an equation to find out how long it will take Ari to finish the race. y = 5 + 6.5x (when y = 50) Determine who will win the race, and determine how far ahead the winner was when he crossed the finish line. Joseph wins by 0.4 seconds (6.5 to 6.9) and is 2.6 meters ahead at the finish line
  6. 6. Intercept Form For each table of values, determine the rate of change and the starting value, then write an equation in intercept form 5 4 3 y 2 1 0 x .03 .02 .01 y 3 2 1 x 11 5 1 y 3 0 -2 x 2 -3 5 y 2 12 -4 x
  7. 7. Intercept Form For each table of values, determine the rate of change and the starting value, then write an equation in intercept form 1; 3; y = 3 + 1x .01; 0, y = 0 + .01x 2; 5; y = 5 + 2x -0.5; 3, y = 3 – 0.5x 5 4 3 y 2 1 0 x .03 .02 .01 y 3 2 1 x 11 5 1 y 3 0 -2 x 2 -3 5 y 2 12 -4 x

  12. 12. Problem Solving <ul><li>Mr. Bress’s son Michael is running in the Philadelphia Marathon in November, and Mr. Bress is trying to figure out where to park his car. There are three lots that are convenient to the start/finish line: </li></ul><ul><li>Landmark Parking charges $5 for the first hour and $2 for each additional hour </li></ul><ul><li>Franklin Park and Lock charges $3 per hour </li></ul><ul><li>Safe and Sound Garage charges $15 for the entire day </li></ul><ul><li>Complete the table, and determine the cost for parking for up to 8 hours at each lot </li></ul><ul><li>Michael assumes that it will take about 3.25 hours to run the race, and he needs about 1.5 hours before the race for check in and warm up. He’ll need about 45 minutes after the race to warm down. Based on the information in the chart, which lot should he choose? </li></ul>
