At the 2010 Winter Olympics, in Vancouver, BC, Usain Bolt won the 100 meters, finishing in 9.69 seconds (a world record.) What was his speed in miles per hour, rounded to the nearest tenth? (1 meter is approximately 39.37 inches.) State the answer in decimal form, rounded to tenths.

I must have missed Mr. Bold running the 100 m at the

And I watched just about everything

To calculate Usain Bolt's speed in miles per hour, we need to convert his distance and time measurements.

First, we need to convert 100 meters to inches. Since there are approximately 39.37 inches in a meter, we can multiply 100 by 39.37 to get 3937 inches.

Next, we need to convert seconds to hours. There are 60 seconds in a minute and 60 minutes in an hour, so there are 60 x 60 = 3600 seconds in an hour. We can divide 9.69 seconds by 3600 to convert it to hours, which gives us approximately 0.0027 hours.

Now, we can calculate the speed by dividing the distance (3937 inches) by the time (0.0027 hours). This gives us approximately 1,458,148.148 inches per hour.

Lastly, to convert inches per hour to miles per hour, we need to divide the result by the number of inches in a mile. Since there are 12 inches in a foot and 5280 feet in a mile, there are 12 x 5280 = 63,360 inches in a mile.

Dividing 1,458,148.148 inches per hour by 63,360 inches per mile gives us approximately 22.98 miles per hour.

So, Usain Bolt's speed in miles per hour, rounded to the nearest tenth, is approximately 23.0 miles per hour.
