Answer 1

To calculate Usain Bolt's average speed in the 100-meter sprint at the 2012 Olympics, we first convert the distance to miles and the time to hours, then divide the distance by the time to get an average speed of approximately 23.21 miles per hour.

Step-by-step explanation:

To calculate Usain Bolt's average speed for the 100-meter race in miles per hour, we need to use the given information to convert meters per second to miles per hour. First, we convert 100 meters to miles by knowing there are about 3.28 feet in a meter and 5280 feet in a mile:

• 100 meters x 3.28 feet/meter = 328 feet
• 328 feet / 5280 feet/mile = 0.0621 miles

Then, we divide the distance in miles by the time in hours (9.63 seconds converted to hours):

• 9.63 seconds / 3600 seconds/hour = 0.002675 hours
• 0.0621 miles / 0.002675 hours ≈ 23.21 miles per hour

So, Usain Bolt's average speed during the 100-meter sprint at the 2012 Olympics was approximately 23.21 miles per hour.
