What is Your Average Walking Velocity?

How will you figure this out?

Rate of travel = Velocity,for our purposes.

If Rate Time Distance, then what is Rate ?

How to Collect Data• Form a group of three people.• The timer will say “go” and call out the time

every 2 seconds for 16 seconds. • The walker will walk steadily for 16 seconds• The marker will walk alongside the walker and

drop a a large paper clip on the floor beside the walker every 2 seconds to designate the position of the walker.

Distance Traveled is a Function of Time

• Measure the distance from each marker to the starting point, noting the corresponding time.

• What are the two variables? Which is the independent variable; which the dependent?

• Make a table and a graph. x= y=

Ready, Set, Go…..

Now pick up the following supplies:• Student Worksheet• 8 markers such as large paper clips• tape measure• time piece
