Question

Is it proportional, inversely proportional or neither?? please explain

John and David are running around the same track at the same speed. When David started running, John had already run 3 laps. Consider the relationship between the number of laps that David run and the number of laps that John has run.

Answer 1

neither

Explanation:

The number of laps John has run is 3 + the number of laps David has run. That is, both numbers are not zero at the same time, so the relationship cannot be proportional.

The numbers have a constant difference, not a constant product, so they are not inversely proportional, either.

David's laps and John's laps are neither proportional nor inversely proportional.
