Praxis 5511 Practice Question
Abibi and Keno run a 10,000-meter race. Abibi runs the first 2,000 meters 16 seconds faster than Keno. If they maintain their pace, how much sooner will Abibi finish?
Correct Answer: C
Rationale: To determine how much sooner Abibi finishes the race, we first analyze their speeds. If Abibi runs the first 2,000 meters 16 seconds faster than Keno, we can express their times for this segment as follows: if Keno's time is T seconds, Abibi's time is T - 16 seconds.
Both runners will maintain their respective paces for the remaining 8,000 meters. Since they both run the same distance, the difference in their initial times will accumulate over the race. Given the calculated difference, Abibi will finish 1 minute and 20 seconds earlier than Keno, making option C the correct choice.
Options A, B, and D represent incorrect time differences based on the calculated speed advantage and the total race distance.
