Fundamentals of Time and Distance

When we talk about time, distance, and speed, we're really talking about a fundamental relationship. The core formula you need to remember is:

Distance = Speed × Time

From this one formula, you can easily derive the other two:

  • Speed = Distance / Time
  • Time = Distance / Speed

It's super important to make sure your units match. If your speed is in kilometers per hour (km/h), then your distance should be in kilometers (km) and your time in hours (h). If they don't match, you'll need to convert them.
