A motorist drives 80km/h at an average speed of 63km/h. Which average is this: mean, mode, median?
this is a stupid question. mean, mode, median relate to collections of data. You have no such set of measurements.
Also, your question is bogus. How can you drive 80 km/h at a speed of 63 km/h?
Pls help me to solve it

Well, if the motorist only drives at one speed, then it seems like the only average we can talk about here is the mean (or the average mean if that makes sense). The mode would be the most frequently occurring speed, and the median would be the middle point between the highest and lowest speeds. But in this case, we only have one speed, so it's all about that mean!
To determine which average is being referred to in this scenario (mean, mode, or median), let's first understand what each average represents:
1. Mean: The mean is also known as the arithmetic average. It is calculated by adding up all the values in the dataset and dividing the sum by the total number of values.
2. Mode: The mode is the value (or values) that appear most frequently in a dataset. In other words, it represents the value(s) that occur with the highest frequency.
3. Median: The median is the middle value in a dataset when it is arranged in ascending or descending order. If there is an even number of values, the median is the average of the two middle values.
Now, let's apply these definitions to the given scenario.
The motorist drives at two different speeds: 80 km/h at certain times and 63 km/h on average. Since there are only two speeds mentioned, there is no dataset to calculate a mean, mode, or median.
Therefore, in this case, none of these averages (mean, mode, median) are applicable.
