To calculate: To find Ann Proctor’s speed in feet per second

Answer to Problem 2CYP
The speed of Ann Proctor in feet per second is 93.72feet/sec
Explanation of Solution
Given: Ann Proctor won the 2007 World Waterski Racing Championship race, where her average speed in miles per hour was 63.9 miles per hour
Formula Used:
1mile=5280feet
Calculation:
Ann Proctor won the 2007 World Waterski Racing Championship race, where her average speed in miles per hour was 63.9 miles per hour
Speed of Ann Proctor in feet per second is calculated as follows:
⇒63.9×52803600feet/sec⇒63.9×1.467feet/sec⇒93.72feet/sec
Conclusion:
Hence, speed of Ann Proctor in feet per second is 93.72feet/sec
