In the first event, the eighth graders are running a baton relay race with three other classmates. The team’s top speed for each leg is 56.81 seconds, 59.22 seconds, 57.39 seconds, and 60.11 seconds. Use the information to predict the team’s best time for the race.
If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points. If not, the seventh graders earn 40 points. Which grade should be awarded 40 points?
Each leg of the race from part a is the same distance. Calculate the team’s average time for each leg of the race. Show your work.
If the team’s average time is less than one minute per leg, then the eighth graders earn . If not, the seventh graders earn . Which grade should be awarded ?
Jill jumped 6 1 3feet in the long-jump event. Jill’s best friend jumped 6 5 7feet. How much farther did Jill’s best friend jump? Describe in words the process you used to solve the problem.
If Jill’s best friend jumped farther than 6.5 feet, then she beat the school record and the seventh graders earn . If not, the eighth graders earn . Which grade should be awarded ?
Claire and her partner, Grace, are throwing for the javelin event as a team. Claire threw the javelin 42 5 8feet and Grace threw it 39 3 5feet. How far did the team throw the javelin? Show your work.
If the total distance of Claire and Grace’s javelin throw is greater than 82.5 feet, then the seventh graders earns . If not, the eighth graders earn . Which grade should be awarded ?
For the high jump, each competitor receives multiple opportunities to clear the bar at each height. On average, Shane completes 2 out of 3 jumps on the lowest bar, 4 out of 6 jumps on the middle bar, and 1 out of 4 jumps on the highest bar. Write an equation that you could use to find Shane’s overall average number of jumps completed. Calculate Shane’s average using the equation.
If Shane’s average number of jumps completed is greater than one-half, then the eighth graders earn . If not, the seventh graders earn . Which grade should be awarded ?
The next event requires each runner to jump 8 hurdles that are spaced 12.3 meters apart. If there are 15 meters from the starting line to the first hurdle and 10.5 meters from the last hurdle to the finish line, how long is the race? Show your work.
15 m 10.5 m Start Finish Myra won the hurdles event for the seventh graders. She completed the race in 22.8 seconds and knocked down 1 hurdle. Byron won the race for the eighth graders. He completed the race in 20.3 seconds and knocked down 3 hurdles. If 2 seconds are added to the finishing time for each hurdle that is knocked down, what is the final time for each runner? Award 1to the team with the fastest time.
The relay race is just over one mile long, approximately 1,760 1 4yards. If Jack and 4 other people each run a leg of the relay, how many yards will each runner run? Justify your answer using an estimation strategy.
The relay was an exciting event! The eighth graders earned 200 points. b) During the shot put event, Alayna throws the ball 32.45 feet while her teammates throw 28.34 feet, 26.59 feet, and 33.11 feet. Use an estimation strategy to determine about how many total feet were thrown by the team. Describe the estimation strategy you used to solve the problem.
If the team threw the shot put more than 110 feet, then the seventh graders earn 1. If not, then the eighth graders earn 1. Which grade should be awarded 1?
Alex, an eighth grader, and Eric, a seventh grader, need to determine who came closer to their grade’s state record for the triple jump. Alex jumped 39.85 feet and Eric jumped 37 feet and 1 1 4inches. Who was closer to the state record if the eighth-grade record is 42.25 feet and the seventh-grade record is 39 feet 3 inches?
If a seventh grader gets closer to the record-setting jump, then the seventh graders earn . If not, the eighth graders earn . Which grade should be awarded ?
The event coordinator asks you to determine how many students participated in the track-and-field day. The total number of students in seventh and eighth grade combined is 584; 5 8of them are seventh graders and 3 8of them are eighth graders. If 4 5of the seventh graders participated in track-and-field day and 7 8of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer. (4 points)
Each team earnsfor each person who participated in the track-and-field day. Who wins the meet—the eighth graders or the seventh graders? Explain.
