A pigeon was 240 meters south of an apartment building. The pigeon then flew north at a constant velocity, and in 15 seconds, it had flown halfway to the apartment building. What was the pigeon’s velocity? Rosie ran directly toward her home at a constant velocity for 78 seconds. In one-third of that time, she ran 52 meters. What was Rosie’s velocity? Anna and Sarah were both competing in the 100 meter dash. They started at one end of the track and raced toward the finish line. Anna ran the first 20.5 meters of the race in 2.5 seconds, and Sarah ran the first 40.0 meters in 5.0 seconds. Assuming both of their velocities remained constant, who crossed the finish line first? Quinn and Shawnak are training for a triathlon. They both swim in Birch Lake as a part of their training. One morning, Quinn swam south at a constant velocity for 12.5 minutes. He swam 615 meters in that time. Later that day, Shawnak swam south at a constant velocity for 10.0 minutes. He swam 484 meters in that time. Who swam at a greater velocity, Quinn or Shawnak? The Ming family and the Harmon family are taking a road trip together but in separate cars. A few hours into the trip, both cars are traveling due east at a constant velocity. During that time, the Ming family’s car traveled 33 miles in 0.6 hours, and the Harmon family’s car traveled 90 miles in 1.5 hours. Which family’s car had the greater velocity? 6. 7. 8. 9. 10.

6. To find the pigeon's velocity, we need to determine the distance it traveled in a certain amount of time. In 15 seconds, the pigeon had flown halfway to the apartment building, so the distance it traveled is 240/2 = 120 meters. The velocity is calculated by dividing the distance by the time: Velocity = Distance/Time = 120 meters / 15 seconds = 8 meters/second. 7. To find Rosie's velocity, we need to determine the distance she ran in a certain amount of time. In one-third of 78 seconds (which is 78/3 = 26 seconds), Rosie ran 52 meters. The velocity is calculated by dividing the distance by the time: Velocity = Distance/Time = 52 meters / 26 seconds = 2 meters/second. 8. To determine who crossed the finish line first, we need to calculate the velocities of Anna and Sarah. Anna ran 20.5 meters in 2.5 seconds, giving her a velocity of 20.5 meters / 2.5 seconds = 8.2 meters/second. Sarah ran 40.0 meters in 5.0 seconds, giving her a velocity of 40.0 meters / 5.0 seconds = 8.0 meters/second. Anna crossed the finish line first as she had a higher velocity. 9. To determine who swam at a greater velocity, we need to calculate the velocities of Quinn and Shawnak. Quinn swam 615 meters in 12.5 minutes, giving him a velocity of 615 meters / 12.5 minutes = 49.2 meters/minute. Shawnak swam 484 meters in 10.0 minutes, giving him a velocity of 484 meters / 10.0 minutes = 48.4 meters/minute. Quinn swam at a greater velocity. 10. To determine which family's car had a greater velocity, we need to calculate the velocities of the Ming family and the Harmon family. The Ming family's car traveled 33 miles in 0.6 hours, giving them a velocity of 33 miles / 0.6 hours = 55 miles/hour. The Harmon family's car traveled 90 miles in 1.5 hours, giving them a velocity of 90 miles / 1.5 hours = 60 miles/hour. The Harmon family's car had a greater velocity.
