Answer:
The best answer is when you increase intensity, time should decrease
Step-by-step explanation:
This is because if your increasing the intensity, then your working harder, just in a low amount of time. Think of it this way- Low intensity=longer time/ then same intensity= same amount of time/ and higher intensity=lower time. the least amount of intensity requires more time to get as much as your trying to get if time and intensity were equal.
If you see where I'm going, you understand, and I hope this helps.
