Answer 1

To find Kevin's average speed in miles per hour, we need to convert the given values into the same unit. Kevin can travel 22 1/2 miles in 1/3 hour. To convert 1/3 hour to minutes, we multiply by 60: 1/3 * 60 = 20 minutes. Now, we can calculate Kevin's average speed: 22 1/2 miles / 20 minutes = 1.125 miles per minute. To convert minutes to hours, we multiply by 60: 1.125 * 60 = 67.5 miles per hour.

Step-by-step explanation:

To find Kevin's average speed in miles per hour, we need to convert the given values into the same unit. Kevin can travel 22 1/2 miles in 1/3 hour. To convert 1/3 hour to minutes, we multiply by 60: 1/3 * 60 = 20 minutes. Now, we can calculate Kevin's average speed: 22 1/2 miles / 20 minutes = 1.125 miles per minute. To convert minutes to hours, we multiply by 60: 1.125 * 60 = 67.5 miles per hour.

Therefore, Kevin's average speed is 67.5 miles per hour, which is closest to option B.65.7 mph.
