![]() ![]() But that’s usually unnecessary in practical life. To get the most accurate mathematically proven average speed, you’d have to calculate the speed at each second of the journey and get the average of all those speeds per second. That’s why it’s an average a rough estimate. The same journey has produced two different average speeds depending on the amount of information we have. ![]() But since he was not actually moving during the lunch break, we leave that part out. His average speed is therefore calculated as we we would normally calculate average. He then covered 150 km in 2 hours which makes his speed 75km/h During the bathroom break, he was not moving so there’s no speed to calculate. Lets’ first calculate the speed in each of the three segments of his journey. Since we have more information about this journey, we can calculate the average speed more accurately. But we know the 200km journey took him 4 hours and that’s all the info we have.Ĭhris covered 50km in one hour, took a one hour lunch break then covered the rest of the journey in 2 hours. We all know that Chris did not drive at a constant speed throughout the journey Infact he probably had a bathroom break on the way. and arrived in Namanga, 200km away at 11:00 a.m. Scenario:Ĭhris started driving from Nairobi at 7.00 a.m. I’ll demonstrate this with two examples of the same scenario. Calculating average speed depends on the information we have. If we had more information about the way the car was moving, then we might come up with a different figure, a more scientific one. ![]() In February this year, the Conservatives put £300,000 into. A look into whether the cameras would be effective on the Island has come back with ‘insufficient evidence’. The brakes have been slammed on a plan to introduce mobile average speed cameras to the Isle of Wight. Because the distance and time taken is all the information we have. Plans for average speed cameras scrapped due to insufficient evidence. Normally this would pass as the average speed. Although we still use the same formula to calculate the average speed. It travels 30 miles in the first hour, 45 miles in the second hour and 75 miles in the third hour. In an example of a car moving from point A to point B, there are speed bumps, straight roads, junctions and all sorts of things to make you slow down and speed through out the journey The speed is hardly constant.įor that reason, we use ‘Average Speed’ to determine speed in which the vehicle (or any other object) was moving. Average speed formula is used to find the uniform rate which involves something travelling at fixed and steady pace. We all know that speed is calculated by dividing the distance traveled by the time taken to cover that distance.īut this is only accurate in a ideal situation where the object traveled at a constant speed from start to finish. ![]()
