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

kobusy [5.1K]

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.

Turn 32/64 into a percent?

alexandr402 [8]

To turn 32/64 into a percent, you have to divide the numerator by the denominator and then multiply the answer by 100.

So, for this question, divide 32 by 64 which is 0.50. Multiply this decimal by 100 and you get 50.

So 50% is the percent for 32/64.

Hope it helps :)
