Concept explainers
To calculate: The rate of swimming of each swimmer and then finding the fastest swimmer.

Answer to Problem 21PPS
Jenny is the fastest swimmer as its speed of swimming is greatest.
Explanation of Solution
Given information: Following table showing event and time taken by different swimmers:
Formula used:Rate of swimming of each swimmer will be calculated using following formula:
Calculation: Rate of swimming of Jenny
Rate of swimming of Dara
Rate of swimming of Kaitlin
Conclusion: Based on above calculation,it is cleared that Jenny covers maximum distance in one second as compared to other swimmers, so Jenny is the fastest swimmer.
