Answer : The Susana swam the fastest.
Step-by-step explanation :
Speed : It is defined as the distance traveled per unit time.
Formula used :
[tex]Speed=\frac{Distance}{Time}[/tex]
First we have to determine speed of the following persons.
For Tawni :
Distance = 50 m
Time = 40.8 s
[tex]Speed=\frac{Distance}{Time}=\frac{50m}{40.8s}=1.225m/s[/tex]
The speed of Tawni is, 1.225 m/s
For Pepita :
Distance = 100 m
Time = 60.2 s
[tex]Speed=\frac{Distance}{Time}=\frac{100m}{60.2s}=1.661m/s[/tex]
The speed of Pepita is, 1.661 m/s
For Susana :
Distance = 200 m
Time = 112.4 s
[tex]Speed=\frac{Distance}{Time}=\frac{200m}{112.4s}=1.779m/s[/tex]
The speed of Susana is, 1.779 m/s
From this we conclude that, in this problem meter affects the response and the speed of Susana is more than the Pepita and Tawani.
Thus, Susana swam the fastest.
