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.

12. • 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

13. Problem 2.5
1. 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 10minute 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.
