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? 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. In practical situations, average speed usually comes up in the context of transportation, such as the average speed of a train or airplane during a trip.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. In physics, velocity measures something’s speed relative to its direction of motion.

Speed is sometimes confused with velocity, but they are not the same. In everyday life, we just call this speed, which is what the speedometer in your car tells you-exactly how fast you’re going at that moment. (Others probably discussed the concept before that, but Galileo usually gets the credit.)Īverage speed should not be confused with instantaneous speed, which measures the speed of an object at a specific instant in time. It didn’t work (light is way too fast to be measured this way), but Galileo did come up with the formula distance/time = average speed. In the 1600s, physicist and astronomer Galileo Galilei tried to calculate the speed of light by measuring how long it would take a person to see a light from across a field. (Which means the next thing you’re going to have to calculate is how to pay the speeding ticket.)Īverage speed might seem like a basic, obvious concept, but for much of history, people didn’t have much of a practical need for such a calculation (plus there were no speedometers on horses). If you were to drive 200 miles in two hours, you could calculate your average speed by dividing the total distance (200 miles) by the total amount of time it took (two hours), giving an average speed of 100 miles per hour. Let’s slow down and start with an example.
