40 kilometer per hour kmh Distance. To work out what the units are for speed you need to know the units for distance and time. The most effective way to remember how to calculate the speed distance or time is to use the following equation.
Distance Speed Time For example a car is travelling at 45 miles per hour for 1 hour 40 minutes.
If you know 2 of the 3 variables the third can be calculated. Your acceleration is 266 meters per second 2 and your final speed is 1463 meters per second. For instance if we have an average speed value thats measured in km per hour and a time value thats measured in minutes you would need to divide the time value by 60 to convert it to hours. The triangles will help you remember these three rules.
