In an attempt to determine the velocity of a person on a bicycle, an observer uses a stopwatch and fi nds the length of time it takes to cover 25 “squares” on a sidewalk. The bicycle takes 4.82 seconds to travel this far. A measurement of one of the squares shows that it is 1.13 m long. What velocity, in m/s, should the observer report?
