what are the equations for speed distance and time. D v x t where v is the velocity average speed t is the time and d is distance so you can read it as Distance Speed x Time. Find the average speed for the whole journey.
The formula for speed is speed distance time. To work out what the units are for speed you need to know the units for distance and time. Rate is distance per time so its units could be mph meters per second or inches per year.
A distance-time graph which shows the speed varying as the time increases is a good way to see how the speed of an object changes.
To solve for speed or rate use the formula for speed s dt which means speed equals distance divided by time. Distance rate x time When identifying the parts of the word problem distance is typically given in units of miles meters kilometers or inches. The math to calculate the distance might look like this. Its expression is as follows.
