Answer:
9.5
Step-by-step explanation:
Probably wrong, but to find average you add up 12+7 then divide by 2, that is 19/2 which is 9.5
The average value of the time is 9.5 minutes.
"The average is defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set".
For the given situation,
Time to walk in the stadium are 12 minutes and 7 minutes.
Number of values = 2
Formula to find average,
Average = Sum of Values/ Number of values
⇒ [tex]Average = \frac{12+7}{2}[/tex]
⇒ [tex]Average = \frac{19}{2}[/tex]
⇒ [tex]Average = 9.5[/tex]
Hence we can conclude that the average value of the time is 9.5 minutes.
