Anne Is Running a 400-Meter Race

question 21

Essay

Anne is running a 400-meter race. She runs at a constant speed of 7.5 meters per second. If you let y denote her distance in meters from the finish line x seconds after the start of the race, y = 400 - 7.5x. Determine b0 and b1 for this linear equation. Find Anne's distance from the finish line 10, 24, and 43 seconds after the race begins. Use these three points to graph the linear equation y = 400 - 7.5x. Use the graph to estimate visually Anne's distance from the finish line 32 seconds after the start of the race.
