Answer:
Option (G)
Step-by-step explanation:
Let the length of the race = a miles
Since, Speed = 
Time taken to cover 'a' miles with the speed = 12 mph,
Time taken '
' = 
Time taken to cover 'a' miles with the speed = 11 mph,
Time taken '
' = 
Since the time taken by David to cover 'a' miles was 10 minutes Or 
hours more than the time he expected.
So, 
a = 22 mi
Therefore, distance of the race = 22 mi
Option (G) is the correct option.
Answer:
σ = 2 (option a)
Step-by-step explanation:
You would want the smallest standard deviation possible.
Think of it like this: if everyone, other than you, got only 50, 51, 52, 53 then you would be the ultimate highest position in the class.
As opposed to being an average position if the scores were about 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60 ---your score would not put you in the highest position in the class distribution.
So, a standard deviation of σ = 2 would give you the highest position in the class distribution.
