Final answer:
In the equation y=5x regarding John's jogging, y represents the distance John jogs in miles. This is a mathematical relationship where y is the dependent variable calculated by multiplying the number of hours jogged (x) by 5, indicating John's pace.
Step-by-step explanation:
In the equation y=5x, y represents the number of miles John jogs. When we analyze equations in mathematics, the convention is that the dependent variable (y) is the outcome or result and the independent variable (x) is the one we have control over or the one we input. In this case, x represents the hours John jogs, which is the independent variable, and thus the one that dictates the value of y, the distance in miles. Since y (the distance John jogs in miles) depends on x (the time in hours), the relationship expressed in the equation is that for every hour John jogs, he covers 5 miles. Therefore, the correct answer to the question is b) The distance John jogs in miles, since y is the number of miles jogged, which is determined by John's jogging pace over a given period.
