Solve the problem. See Example 2.

Track Event Speeds  At the 1996 Olympics, Donovan Bailey (Canada) set what was then the world record in the 100-m dash with a time of 9.84 sec. Refer to Exercise 25, and answer the questions using Bailey’s time. (Source: The World Almanac, 2000.)

Exercise 25

Solve the problem. See Example 2.

Track Event Speeds  On September 14, 2002, Tim Montgomery (USA) set a world record in the 100-m dash with a time of 9.78 sec. If this pace could be maintained for an entire 26-mi marathon, what would his time be? How would this time compare to the fastest time for a marathon of 2 hr, 5 min, 38 sec? (Hint: 1 m ≈ 3.281 ft.) (Source: The World Almanac, 2003.)
