In this activity we want to estimate how fast we walk. Measure a room or hallway with your steps by walking with one foot touching the next step. Measure your shoe with a ruler in inches. Calculate the length of the room in inches. In part you will use your phone timer and will walk normally from one side of the room to the other and will record your time in minutes and seconds. Calculate the time in seconds. If you divide your distance over the time, you will get a walking speed in inches/s. Convert your speed to m/s. 11.375 is my inches for my shoe size. i took 13 steps across in the room and it took me 4.49 sec
