![]() The general speed average formula for an object is given as. What will Be the General Average Speed Formula for an Object? ![]() The average speed of the runner is 2.5m/s. So, applying the general formula for the average speed Solution: Total distance covered by the runner = 100 meters What isu000bthe average speed of the object Example 8.2 - The Odometer of a car reads 2000 km at the start of a trip and 2400 km at the end of the trip. Calculate the average speed of the runner. Example 8.1 - An object travels 16 m in 4 s and then another 16 m in 2 s. After the finish of the first lap, he reached back to the starting point. To understand how to use the formula for average speed let us consider an example.Įxample: A runner completes a 100m lap in 40 sec. How To Use the Formula for Average Speed? To calculate the time, the average speed formula will be molded as. The general average speed formula is given as How To Calculate Time Using Average Speed Formula? To calculate the distance, the average speed formula can be molded as. The general formula for average speed is given as Using average speed formula = Total distance traveled ÷ Total time takenĪnswer: Average speed of a car is 43.57 m/s.įAQs on Average Speed Formula How To Calculate Distance Using Average Speed Formula? Calculating average speed distance travelled is measured in metres (m) average speed is measured in metres per second (m/s) time is measured in seconds (s). ![]() Calculate the average speed using the average speed formula. The product of \(s_1 \times t_1 \), and \(s_2 \times t_2 \) gives the distances covered in time intervals \(t_1 \), and \(t_2 \) respectively.Īverage Speed Formula \(= \frac\)Īverage Speed = (80 × 4 110 × 3) ÷ (4 3)Īnswer: The average speed of the train is 92.86 miles/hour.Įxample 3: A car travels at a speed of 45 km/hr for 5 hours and then decides to slow down to 40 km/hr for the next 2 hours. ![]() The formula for average speed is given as: Average Speed Formula:Īverage Speed = Total distance covered ÷ Total time takenĬase 1: For a body or object traveling with a speed of \(s_1 \) for time \( t_1 \), and the speed of \(s_2 \) for time \( t_2 \), the formula for average speed is given in the below expression. The average speed of a body is equal to the total distance covered, divided by the total time taken. Even with varying speed, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion. Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. ![]()
