mean is just average of the total means x1+x2+x3 /3 = x while median is the number where half of the numbers in that set is larger and other half is smaller and example will be 1, 5 , 7, 9 , 100 while median will be 7 because there are 2 greater and two smaller number in the set while mean will be 61.

#2: Median speed.
