Question

The results of a swim meet are shown. Who swam the fastest? Explain your reasoning.

Answer 1

Answer : The Susana swam the fastest.

Step-by-step explanation :

Speed : It is defined as the distance traveled per unit time.

Formula used :

$Speed=\frac{Distance}{Time}$

First we have to determine speed of the following persons.

For Tawni :

Distance = 50 m

Time = 40.8 s

$Speed=\frac{Distance}{Time}=\frac{50m}{40.8s}=1.225m/s$

The speed of Tawni is, 1.225 m/s

For Pepita :

Distance = 100 m

Time = 60.2 s

$Speed=\frac{Distance}{Time}=\frac{100m}{60.2s}=1.661m/s$

The speed of Pepita is, 1.661 m/s

For Susana :

Distance = 200 m

Time = 112.4 s

$Speed=\frac{Distance}{Time}=\frac{200m}{112.4s}=1.779m/s$

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.
