Answer 2

Answer:

E. 1/ 20 seconds

Step-by-step explanation:

The distance covered by both the athletes is the same.

So, calculating the difference between their times:

• Bryan completed the race in 11.74 seconds
• Luis completed the race in 11.69 seconds

DIFFERENCE:

That means, Luis completed the race before Bryan, and the difference between their times is:

= 11.74 - 11.69

= 0.05 seconds

CONVERSION:

To convert this decimal into a fraction we'll multiply and divide the decimal by 100 (as the number of decimal places is "2", the decimal will be handled by 10 exponent "2" )

$=0.05 \times \frac{100}{100}$

$= \frac{5}{100}$

5's a common factor in both numerator and denominator hence, it cancels out

$=\frac{1}{20}$

ANSWER:

Therefore, we got $\frac{1}{20}$ seconds. That is option E.
