  2. Snyder students drove 700 km from PA to MA. They left at 7 am and arrived in MA at 3 pm. The students visited an aquarium for 2 hours during the trip. A. What was their average speed while they were on the road? (show all work)

  3. V= d/t • V= 700 km/ 6 hr • V= 116.6 km/hr

  4. Snyder students drove 700 km from PA to MA. They left at 7 am and arrived in MA at 3 pm. The students visited an aquarium for 2 hours during the trip. • B. What was their average speed on the way to MA? (show all work)

  5. V= d/ t • V= 700 km/ 8hr • V= 87.5 km/hr

  6. 2. Gus and Sally have a race. They race to the park and back. The park is 5 km away. Gus takes 20 minutes to get to the park and 15 minutes to get home. Sally takes 18 minutes to get to the park and 16 minutes to get home. • A. Whose leg- to or from the park- was the fastest? (show all work)

  7. V= d/t • V= 5/15 • =.33 • V= 5/20 • =.25 • V= 5/18 • .27 • V= 5/16 • =.31

  8. 2. Gus and Sally have a race. They race to the park and back. The park is 5 km away. Gus takes 20 minutes to get to the park and 15 minutes to get home. Sally takes 18 minutes to get to the park and 16 minutes to get home. • B. Which person had the faster average speed for the whole trip to the park and back? (show all work)

  9. V=d/t • V= 10/35 • =.28 • V= 10/34 • =.29

  10. 3. I took a trip to Hawk Mountain. I left at 10 am and drove 50 km. I stopped half way (around noon) to change a flat tire. That took 20 minutes. I arrived at my destination at 1 pm. • A. Create a data table • B. Make a distance graph • C. Make a position graph
