One Last Time:  The Last Week of the Olympics - The Solutions

 

October 1, 2000


A person jogging 8-minute miles jogs 7.5 miles in 1 hour, and 7.5 miles is equal to 7.5 x 5280 = 39,600 feet, or 39,600 x 12 = 475,200 inches. And there are 60 x 60 = 3600 seconds per hour, so there are 3600 x 100 = 360,000 hundredths of a second in an hour. Consequently, in 1/100 second, she will jog 475,200 / 360,000 = 1.32 inches.

If the bullet goes 8 feet in 1/100 of a second, it will go 800 feet in 1 second. Since there are 60 x 60 = 3600 seconds in an hour, the bullet will travel 3600 x 800 = 2,880,000 feet in one hour. There are 5280 feet in a mile, so the bullet travels 2,880,000 / 5280 = 545 miles per hour.
