They increase through the day.
11 - Noon - most, 15 bags1 - 2 - least, 0 bags
See graph above. Time is independent so it goes on the x-axis.

No, Ken did 72 and Andrea did 110.
The scales are different; Andrea’s scale counts by 20’s and Ken’s count by 10’s.

The group traveled 45 miles in 5 hours.
They went the farthest from 0 - 0.5, and the least from 3.5 - 4.5.
They went farther the first half, 27 miles.

What did you learn?
1)Which variable is displayed on the x-axis? 2)What is the least value on the X-axis?
What is the greatest value on the x-axis?
3) Why is it reasonable to have the size of the intervals for the x-axsis be 0.5 hours? 4) Which variable is displayed on the y-axis?
5) What is the least value on the y-axis? What is the greatest value on the y- axis?
6) What is the size of the interval for the y-axis?
7) Did anyone use an interval other than 5 miles for the y-axis?
