  1. Tuesday’s Warm Up

  2. Motion Problem Set Ups 1. A passenger train’s speed is 60 mi/h, and a freight train’s speed is 40 mi/h. The passenger train travels the same distance in 1.5 h less time than the freight train. How long does each train take to make the trip?

  3. Motion Problem Set Ups 2. Marla begins walking at 3 mi/h toward the library. Her friend meets her at the halfway point and drives her the rest of the way to the library. The distance to the library is 4 miles. How many minutes did Marla walk?

  4. Motion Problem Set Ups 3. Lois rode her bike to visit a friend. She traveled at 10 mi/h. While she was there, it began to rain. Her friend drove her home in a car traveling at 25 mi/h. Lois took 1.5 h longer to go to her friend’s than to return home. How many hours did it take Lois to ride to her friend’s house?

  5. Motion Problem Set Ups 4. Fred begins walking toward John’s house at 3 mi/h. John leaves his house at the same time and walks toward Fred’s house on the same path at a rate of 2 mi/h. How long will it be, in minutes, before they meet if the distance between the houses is 4 miles?

  6. Motion Problem Set Ups 5. May rides her bike the same distance that Leah walks. May rides her bike 10 km/h faster than Leah walks. If it takes May 1 h and Leah 3 h to travel that distance, how fast does each travel?

  7. Motion Problem Set Ups 6. A train leaves the station at 6:00 P.M. traveling west at 80 mi/h. On a parallel track, a second train leaves the station 3 hours later traveling west at 100 mi/h. At what time will the second train catch up with the first?

  8. Motion Problem Set Ups 7. At 10:00 A.M., a car leaves a house at a rate of 60 mi/h. At the same time, another car leaves the same house at a rate of 50 mi/h in the opposite direction. At what time will the cars be 330 miles apart?

  9. Motion Problem Set Ups 8. It takes 1 hour longer to fly to St. Paul at 200 mi/h than it does to return at 250 mi/h. How far away is St. Paul?

  10. Tuesday Night’s Homework Solve Each of today’s worksheet problems

  11. Wednesday Warm Up The Charlestown Chiefs football team scored 10 times for a total of 46 points. If a touchdown is worth 7 points and a field goal is worth 3 points, how many touchdowns and how many field goals did the Chiefs score?

  12. Two jets leave Dallas at the same time and fly in opposite directions. One is flying west 50 mi/h faster than the other. After 2 hours, they are 2500 miles apart. Find the speed of each jet. How are the distances that the two jets fly related Distance flown by 1st Jet + Distance flown by 2nd jet = 2500 mi

  13. Two jets leave Dallas at the same time and fly in opposite directions. One is flying west 50 mi/h faster than the other. After 2 hours, they are 2500 miles apart. Find the speed of each jet. How are the times that the two jets fly related The time of flight of 1st Jet = The time of flight of 2nd Jet

  14. Two jets leave Dallas at the same time and fly in opposite directions. One is flying west 50 mi/h faster than the other. After 2 hours, they are 2500 miles apart. Find the speed of each jet. How are the speeds of the two jets fly related Speed of Westbound Jet = Speed of Eastbound Jet + 50 mi/hr

  15. Two jets leave Dallas at the same time and fly in opposite directions. One is flying west 50 mi/h faster than the other. After 2 hours, they are 2500 miles apart. Find the speed of each jet. Define: Let x = the speed of the jet flying east. Then x + 50 = the speed of the jet flying west. Relate: eastbound jet’s plus westbound jet’s equals the total distance distance distance Jet Rate Time Distance Traveled Eastbound x 2 2x Westbound x + 50 2 2(x + 50) Write: 2 x + 2( x + 50 ) = 2500 Eastbound Westbound

  16. Two jets leave Dallas at the same time and fly in opposite directions. One is flying west 50 mi/h faster than the other. After 2 hours, they are 2500 miles apart. Find the speed of each jet.

  17. Two jets leave Dallas at the same time and fly in opposite directions. One is flying west 50 mi/h faster than the other. After 2 hours, they are 2500 miles apart. Find the speed of each jet. Jet Rate Time Distance Traveled Eastbound x 2 2x Westbound x + 50 2 2(x + 50) Eastbound Westbound
