3. Warm-Up Show all work – Let statements, diagram, table, equation/solve, write answer in a full sentence. A truck traveling 45 miles per hour and a train traveling 60 mph cover the same distance. The truck travels 2 hours longer than the train. How many hours does each travel. The truck travelled for 8 hours and the train travelled for 6 hours.

4. Quick Re-Cap There are 3 different types of uniform motion problems we will encounter! Objects going in the same direction Objects going in the opposite direction Objects going round trip

5. Station Activity 6 groups of 4 Ask for help if your group gets stuck Answer key is provided at each station

6. Round 1 Mrs. Hicks and Ms. Lee are both leaving from school and travel in opposite directions. Mrs. Hicks averages 45 miles per hour and Ms. Lee averages 30 miles per hour. In how many hours will they be 900 miles apart?

7. Round 2 Pritika and Meghana are about to meet up to work on their math homework. They’re currently 1980 yards away from one another. If they travel 80 and 85 yards a minute respectively, in how many minutes will they meet?

8. Round 3 Katniss is leaving the Capitol and is traveling back to district 12 on the train which travels 30 miles per hour. Four hours later, President Snow leaves the Capitol to catch up with Katniss on a hovercraft which travels 60 miles per hour. How many hours will it take President Snow to catch up to Katniss?
