# How Do You Calculate Speed Per Hour?

Speed per hour is the average distance something moves in a given period of time. It can be measured as average velocity or instantaneous speed and is usually expressed in units such as miles per hour (mph) or kilometers per hour (km/h).

There are many different ways to calculate speed, but one of the easiest and most commonly used methods is the speed equation s=d/t. This is also known as the speed formula triangle, and it will help you to memorise the relationship between the three variables – distance, speed and time.

This formula is used in a variety of ways, so it’s important to be familiar with it. You can use it to answer questions about distance, time and speed, or as a guide when working out answers to other calculations.

You can find out how to use the formula triangle by downloading our free practice test for Edexcel GCSE Level 1 Mathematics and Science exams, which are based on the latest exam papers. These tests contain lots of questions about distance, speed and time, so they’re a great way to boost your confidence in answering these types of questions.

When you’re using the speed equation to calculate distance, make sure you convert the units of distance and time accordingly. This is especially important when you’re calculating average speed, as you may be asked to use different units.

Alternatively, you can use the speed equation to solve for distance, and then use another formula to find speed. This is the most common way to do this, but you can also use a calculator that will automatically do this for you.

A good way to remember the speed equation is to write it on a piece of paper. This will help you to remember it and will make it easier for you to use in your exams.

#### The difference between speed and velocity

There is a lot of confusion around the meaning of these two terms. The main difference is that speed is a measure of an object’s speed at a particular time while velocity is a measure of the rate at which an object changes position. This is a very important distinction to understand because the term speed can be confusing and difficult to remember.

In the GCSE course, you will often be asked to calculate either a constant speed or an average speed. This is because speed varies throughout a journey, and it may include acceleration and deceleration.

To calculate an average speed, you’ll need to know the total distance covered and the time it took to traverse that distance. You can also use the speed equation to work out a constant speed, but remember that constant speed is only when an object’s speed remains the same over time.
