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:
#1 is 30 degrees
#2 is obtuse
#3 is "No rhombuses are rectangles"
#4 is D
#5 is A
Step-by-step explanation:
For #1, we have an angle vertical to 120 degrees which includes a right angle, so we make an equation:
90+x=120
x=30
So angle x is 30 degrees aka. Option A
For #2, obtuse angles have the sum of the square of the side lengths that are less than the square of the hypotenuse. In this case, 6^2+4^2<9^2 or 50<81
For #3, rhombuses have two pairs of congruent sides but no right angles while rectangles have two pairs of congruent sides but they also have right angles.
For #4, they are similar because one of the triangles is dialated by a scale factor of 1.5.
For #5, just think of turning the triangle on its other side, aka. option A
