Question from Niecey:

If Greg was timed at 0.91 seconds for 10 meters running the 100 meter dash, at that speed, could he pass a car traveling 15 miles per hour in a school zone?

The remaining unites are miles/hour. You can fill in the appropriate numbers in the empty boxes and complete the calculation.
