  1. For the following RipStik velocity chart:
    Graph f(x) = 300x + 500 RipStik time versus distance Time (seconds) Distance (centimeters) x-axis labels 0 1 2 3 4 5 6 7 8 9 10 y-axis labels 0000 1000 2000 3000 4000
    1. __________ _____ Determine the velocity ѵ of the RipStik.
    2. __________ _____ If the RipStik continued at that velocity for 20 seconds, how many centimeters would the RipStik travel?
    3. __________ _____ If the RipStik continued at that velocity for 8600 centimeters, how many seconds would the RipStik travel?
  2. Tulpe walked 6150 centimeters in 50 seconds.
    1. __________ _____ Calculate Tulpe's speed in centimeters per second.
    2. _______________ Is Tulpe faster or slower than 213 cm/s speed of the RipStik on Monday?.
    3. __________ seconds. How long in seconds for Tulpe to walk 100,000 centimeters?
    4. ________ minutes ________ seconds. Convert Tulpe's time to walk 100,000 centimeters from seconds to minutes and seconds.
  3. __________ _____ A runner runs a five kilometer race in 30 minutes. What is their speed in centimeters per second?
