### Transfer 27ft 2 5/16 to centimeters.

816
Explanation
To convert 27ft 2 5/16 to centimeters, we need to first convert feet to inches and then inches to centimeters. There are 12 inches in a foot, so 27ft is equal to 27 * 12 = 324 inches. Next, we add the 2 5/16 inches to get a total of 326 5/16 inches. Finally, we convert inches to centimeters by multiplying by 2.54 (since 1 inch is equal to 2.54 centimeters). Therefore, 326 5/16 inches is equal to 326.3125 inches. Multiplying this by 2.54 gives us 826.915625 centimeters, which rounds to 816 centimeters.

### The distance bettween Kayla's house and Betty's house is 3 1/2 miles. It takes Kayla 50 minutes to get to Betty's house. What is the speed in km/h?

6.72
Explanation
To find the speed in km/h, we need to convert the distance from miles to kilometers and the time from minutes to hours. Since 1 mile is approximately equal to 1.60934 kilometers, we can multiply 3.5 miles by 1.60934 to get the distance in kilometers. Next, we divide the time of 50 minutes by 60 to convert it to hours. Finally, we divide the distance in kilometers by the time in hours to get the speed in km/h. The result is 6.72 km/h.
