To compare their speeds we must first display them so that they each represent feet per second.

To do this simply divide total distance (feet) by time (seconds). This gives you there feet per second.

Stephanie: 9/s

Ron: 255/22 or 11.590/s

Liz 1000/362 or 2.762/s

Emily 605/60 or 10.083/s

Therefore Ron ran the at the fastest speed.
