Milepost equation

Have you ever gone on a long car ride? And have you noticed those signs on the side of the road that tell you how far away you are from a certain city or landmark? Those signs are called mileposts. And the milepost equation is simply a formula that helps calculate how far away you are from a certain milepost.

Okay, let's make it simpler. Let's say you're in the car with your parents and they tell you that you are 50 miles away from grandma's house. But you see a milepost that says you are at milepost 25. This means you're halfway there! And the milepost equation helps you figure out that 25 miles to milepost 50.

The equation looks like this: distance to milepost = current milepost - previous milepost.

For example, let's say you started at milepost 10 and now you're at milepost 20. If you use the milepost equation, you can figure out that you've traveled 10 miles so far (20-10=10).

Overall, the milepost equation is just a simple way to calculate how far you've traveled on a road trip based on the mileposts you pass.
