The Question

An Olympic sprinter runs the 100-meter dash in 9.50 seconds. Determine the average speed of the runner in m/s. Enter a numerical answer (no units) accurate to the second decimal place.

(Note: Numbers are randomly generated and may differ from those shown here.)

Formula Fix

The average speed (vave) of an object can be determined as the ratio of the overall distance traveled (d) per time of travel (t):
 
ave. speed = distance / time
vave= d / t

A Very Fine Detail

The Minds On Physics program calculates answers accurate to many decimal places. Your answer does not need to be that precise. The program will allow you to have a 1% deviation from the right answer without being wrong. This means you should enter your answer to at least the second decimal place.
