Day 5: Norfolk to Williamsburg

• The last stop on the Ocean and History Bike Tour was Williamsburg, Virginia. In America’s colonial period, Williamsburg was the capital of Virginia. The buildings of that period have been restored so visitors can imagine what life was like there in the eighteenth century.

• After the riders finished lunch, they decided to have a race. The winner would receive $50 from the tour company’s first profits. Theo had an electronic speedometer on his bike. It recorded his speed every 10 minutes during the 90- minute race

Problem 2.51. What was Theo’s fastest recorded speed, and when

did it occur?2. What was Theo’s slowest recorded speed, and when

did it occur?3. Describe the changes in Theo’s speed during the race.4. The graph only shows his speed at 10 minute

intervals, it does not tell us what happen between 10-minute marks. The paths below show 5 possibilities of how his speed may have changed during the first 10 minutes. Explain in writing what each connecting path would tell about his speed.
