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
<h3><em>DIFFERENCE:</em></h3>
That means, Luis completed the race before Bryan, and the difference between their times is:
= 11.74 - 11.69
<u>= 0.05 seconds</u>
<h3><em>CONVERSION:</em></h3>
To convert this decimal into a fraction we'll multiply and divide the decimal by 100 (<em>as the number of decimal places is "2", the decimal will be handled by 10 exponent "2" </em>)
<em>5's a common factor in both numerator and denominator hence, it cancels out</em>
<h3><em>ANSWER:</em></h3>
Therefore, we got seconds. That is option E.
