  1. For the following RipStik velocity chart:
    Graph f(x) = 300x 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 30 seconds, how many centimeters would the RipStik travel?
    3. __________ _____ If the RipStik continued at that velocity for 5700 centimeters, how many seconds would the RipStik travel?
  2. Tulpe jogged 24200 centimeters in 121 seconds.
    1. __________ _____ Calculate Tulpe's speed in centimeters per second.
