    • What's the Inverse Variation or Indirect Proportionality Formula?What's the Inverse Variation or Indirect Proportionality Formula?

    What's the Inverse Variation or Indirect Proportionality Formula?

    Ever heard of two things being inversely proportional? Well, a good example is speed and time. The bigger your speed, the less time it takes to get to where you are going. So when one variable is big, the other is small, and that's the idea of inverse proportionality. But you can express inverse proportionality using equations, and that's an important thing to do in algebra. See how to do that in the tutorial!
