Bryan completed a 100-meter race in 11.74 seconds. Luis completed the same race in 11.69 seconds. What was the difference betwee
son4ous [18]

Answer:

\frac{1}{20} of a second

Step-by-step explanation:

We can convert each time into fractions.

11.74 is the same thing as 11 \frac{74}{100}

and 11.69 is the same thing as 11 \frac{69}{100}.

We know that 11 - 11 = 0, so we can focus on the fractions for now.

Let's subtract \frac{69}{100} from \frac{74}{100}.

\frac{74}{100} - \frac{69}{100} = \frac{5}{100}.

We can now simplify \frac{5}{100} by dividing both the numerator and denominator by 5.

\frac{5\div5}{100\div5}  = \frac{1}{20}.

Hope this helped!
