Answer:
(1,4.5)
Step-by-step explanation:
the midpoint of -2 and 4 is 1
the midpoint of 0 and 9 is 4.5
The answer is x=32 degrees
d=rt
r = 9 1/2 as an improper fraction (2*9 +1)/2 = 19/2
t = 1 3/4 as an improper fraction (4*1+3)/4 =7/4
d=rt
d = 19/2* 7/4 = 133/8
8 goes into 133 16 times with 5 left over
16 5/8 miles
