D = R x T D = 8.4mph x 1 hour We know that T = 1 hour because the problem told us so. This stands for Distance = Rate x Time. As the average of the 5 quantities is 6 and the average of three of these five is 8, the average of the remaining two should be a value that is If 0 < a < b < c, which of the following must be equal to b ? (a+c)/2 (a+c)/3 (c-a)/2 (c-a)/3 (Saturday/1.2002 #17 ) p. 610 A. (a+c)/2 TEST navigate here
Knowing this, let us try an example: Example 3: Find the mean of these numbers: 3, −7, 5, 13, −2 The sum of these numbers is 3 − 7 + 5 For the middle part of the trip, we know that D = 10mph x 3 hours, so we know that D = 30 miles. Average of these two quantities = = 3. What is the tenth number ? 0 9/10 10/9 9 10 A. http://www.mathsisfun.com/mean.html
