  • 1. Uniform MotionWord problems using rate, time and distance.

2. Uniform Motion An object that moves at a constant speed or rate is said to be in Uniform Motion. 3. Uniform Motion Uniform motion problems use thedistance formula.R x T = D Rate (how fast) Time (how long) Distance (how far) 4. Uniform MotionThere are 3 basic types of problems:1) Objects moving in the same direction2) Objects moving in opposite directions3) Objects that travel a round-trip situation 5. Uniform Motion Same Car 1directionCar 2 Oppositedirections Round-trip 6. Uniform Motion A car and a truck leave a tollbooth at the sametime and travel to a rest area. The car travels15 mi/h faster than the truck and makes the tripin 3 hours. The truck makes the trip in 4 hours.What is the rate of the truck?RxT=DCARTRUCK 7. Uniform Motion Two cars travel in opposite directions from atollbooth at the same time. The average rate ofspeed of the eastbound driver is 10 mi/h fasterthan the westbound drive. If they are 200 milesapart after 2 hours, what is the average rate ofspeed of each car?Rx T= DCAR -ECAR - W 8. Uniform Motion A car and a truck travel in opposite directions.The car, traveling at 60 mi/h, takes 1 hour lessto go the same distance as the truck, whichtravels at 50 mi/h/ How long does the trucktake to go the distance?Rx T=DCARTRUCK 9. Uniform Motion A jet leaves the base at 9:00 AM and flies at 500mi/h. At 10:30 AM, a second jet takes off on thesame heading and flies at 650 mi/h. How long will ittake the second jet to overtake the first?RxT=DJet 1Jet 2 10. Assignment: Worksheet # 1,3,4 and show the RTD chart for each.
