Question
Your classmate makes a claim. They say that the highest instantaneous speed that Bolt reached must have been within the twenty-metre segment where his average speed was highest.Explain whether your classmate's claim is correct or not.
Solution
Your classmate's claim is not necessarily correct. While it might seem logical to assume that the highest instantaneous speed would occur within the segment where the average speed was highest, this is not always the case.
Here's why:
-
Average speed is calculated by dividing the total distance traveled by the total time taken. It does not account for variations in speed within that distance.
-
Instantaneous speed, on the other hand, is the speed at a specific instant in time or at a specific point in the journey.
-
Therefore, it's possible that Bolt could have reached his highest instantaneous speed outside of the twenty-meter segment where his average speed was highest. For example, he might have started off slower in that segment and then accelerated towards the end, resulting in a high average speed. But his highest instantaneous speed could have occurred elsewhere, where he sprinted at his fastest for a brief moment.
-
So, without additional information about Bolt's speed at each point in his run, we cannot definitively say that his highest instantaneous speed occurred within the twenty-meter segment where his average speed was highest.

Karl was suspicious that cars driving down his street were often driving faster than the speed limit of 25mph. He called the police department and complained. In response the police department set up a radar speed sign (shown in the image below) and recorded the speeds of vehicles for a day.Here is the report they obtained after observing speeds for a day.Mean Speed 28.2 mphMinimum Speed 18 mphMaximum Speed 43 mphMedian Speed 25 mph90th Percentile of Speed 33.1 mph Which of the following would be a correct statement to make about the information shown in the above report?Group of answer choicesThe fastest car observed was driving 28.2 mph.One in every 10 of the vehicles observed (10%) was driving faster than 33.1 mph.The typical speed of vehicles that day was around 18 mph.The average speed of 28.2 was under the speed limit, so it seems that, at least on average, cars are going the correct speed.Cars all appear to have been driving very quickly that day as the slowest vehicle speed recorded was still higher than the speed limit.
