Determine the average speed of a runner in mph, from a track run distance in metres, and the stopwatch time in minutes or seconds. Calculate the percent error for each average speed measurement using the theoretical formula value (Percent error theoretical value - measured value /.

Suppose a sports car reaches a speed maximum speed of 250 km/h. The average speed is certainly different from the top or maximum speed.

Convert a journey distance in kilometres and the time taken in hours, to an average speed in mph. Average speed is an interesting concept in mathematics and physics.First choose two points that lie the line - say point A is (0, 0) and point B is (10, 50). To find the speed of an object from a distance-time graph, we need to calculate the gradient (or slope) of the line. ApplicationsД®xamples of types of average speed calculations: Calculating the speed from a distance-time graph. This is the speed that a moving object would need to maintain without variation, in order to complete the distance travelled in the same period of time. In contrast, a cars speedometer shows its instantaneous speed, that is, the speed determined over a very small interval of time an instant. This is the quantity we calculated for our hypothetical trip. Read it as 'vee bar is delta ess over delta tee'. Time TakenД®nter the time taken to complete the distance travelled in any measurement unit of time. The bar over the v indicates an average or a mean and the (delta) symbol indicates a change. This tool calculates average speed using the following formula:Д®nter the actual distance that is travelled by a moving object in any unit of distance measurement. Once you have entered a distance and a time period the average speed will appear in the answer box and two conversion scale will also show a range of values for distance versus speed and time versus speed. Convert time duration into different unitsД¬alculate average speed of a moving object from the total distance travelled and the time taken from start to finish.
