In 1996 Ato Boldon of UCLA ran the 100-meter dash in 9.92 seconds. In 1969 John Carlos of San Jose State ran the 100-yard dash in 9.1 seconds. Which runner had the faster average speed?

We convert yards to meters using our conversion calculator and we get:
100 yards = 91.44 meters

Now we set up a proportion of time per meter:

• Ato Boldon: 9.92/100 = 0.992 per meter
• John Carlos: 9.1/91.44 = 0.995 per meter

Since Ato Boldon's time was less per meter, he had the faster average speed
