Presentation Transcript

  1. Warm Up Define a variable, write an equation and solve. 1. The sum of three consecutive integers is 117. Find the integers. 2. The length of a rectangular garden is 6 less than three times the width. If you have 44 yards of fencing, find the dimensions of the garden.

  2. Uniform Motion Equal Distances

  3. Objective • TSWBAT manipulate the equation D=rt to find uniform motion.

  4. Uniform Motion: when an object moves at a constant rate. Rate x Time = Distance R x T = D

  5. Catch Up Kevin Pedro

  6. A group of campers and one group leader left a campsite in a canoe. They traveled at an average rate of 10 km/h. Two hours later the other group leader left the campsite in a motorboat. He traveled at an average rate of 22 km/h. How long did the motorboat travel in order to with the first group? catch up

  7. Carl leaves his house on a bicycle at 9:30 am and averages 5 mph. His wife, Karen leaves at 10:00 am, following the same path and averaging 8 mph. How long will it take for Karen to catch up with Carl.

  8. There and Back Polly

  9. Jessica rides out into the country at a uniform rate of 30 mph. She rests for 2 hours and then rides back at 20 mph. She is gone for 5 hours. How far did she go?
