Answer:
The mean of the data is 21.41
Step-by-step explanation:
To find the mean of a data set you must...
Add up all data values to get the sum
Count the number of values in your data set
Divide the sum by the count
Since the train travels 50 miles in 1 hour, to find 3/4 of an hour:
3/4 * 50
75/2 miles
Hope this helps!
So you would divide 43.65 by 5 hours (to get 8.73), then you multiply by 7, and your final answer is $61.11
Hope that helps :)
