Answer:
A. 5 meters every 3 seconds or 1,667 meters every second
B. No. He is not fast enough to cover the distance required on the time specified by the judges or the event
C. Yes. He has more time to cover the distance in this event, so his current average speed is enough for him to have the opportunity to qualify.
Step-by-step explanation:
The statement tells us that Xavier Swims at a constant speed of 5/3 meters/second. This means that every 3 seconds, Xavier travels 5 meters. It can also be considered that Xavier swims 1,667 meters every second.
To complete 100 meters on 55 seconds, Xavier would have to Swim 1,82 meters every second, dividing 100 meters between 55 seconds. Currently, Xavier can´t achieve that speed so he would not qualify. However, on the 200-meter event he has more time to cover the distance and would need to swim 1,54 meters every second wich is below its current speed. To the second event, Xavier might qualify.
