The Big Race Greta Haskell Eliza Macneal Allison Mark Luta Lipman 8-6
Story • One day, Luta, Greta , eliZa, and Allison decided to race each other. Greta skipped, eliZa ran, Allison walked, and Luta hopped. Luta got a ten foot head start, Allison got a five foot head start, and eliZa got a three second delay. In the race, Greta ran fifty-feet in six seconds. Allison walked forty-five feet in nine seconds. Luta hopped forty feet in seven seconds. And eliZa ran fifty feet in three seconds after her three second delay. Therefore Greta’s equation was Y=50/6x, Allison’s was Y=45/9x+5, Eliza’s was Y=50/3x-50, and Luta’s was Y=40/7x+10.
Equations • Eliza ran 50 feet and her slope is related because it shows how many feet she runs a second. Her y-intercept is -50 because she started from 3 seconds later. She started 3 seconds late so her starting point is (3,0) • Greta skipped 50 feet and her slope is related because it shows how many feet she skipped per second. Her y-intercept is 0 because she started at (0,0) • Luta hopped on one foot for 40 feet. The slope represents how many feet she hopped in one second. The y-intercept it 10 because she started 10 feet ahead. • Allison walked 45 feet, her slope represents how many feet she walked per second. Her y-intercept is 5 because she started 5 feet ahead.
