Answer and Explanation:
A. The time recorded is a continuous variable because it is necessary to determine that time through a measurement process, thus allowing the time spent by each runner to be measured and the comparison between the time shown by them at the end of the race.
B. The recorded time is a variable with a ratio scale because it has a true zero point, which is the basis for measuring time. This type of scale only occurs with the existence of this zero point, which can be related to many elements such as weight, speed, height, among others.
