Answer: the average speed is 7.5 mph or at least im pretty sure
Step-by-step explanation:
This is because if you make the 2 miles at 6 mph to 1 mile at 3 mph then you get 1 mile at 3mph and 1 mile at 12 mph. now that you have the unit rates of these you can add them. 1 + 1 = 2 miles and 3 + 12 = 15 mph now divide this by two and you get 7.5 mph per mile.
I hope this helped, if it did could you give me a good rating? lol

Answer:
The value of 
Step-by-step explanation:
Given that  
now to find  from the given functions f(x) and f'x
 from the given functions f(x) and f'x
let 
Then put x=1 in above function we get

 (from the table f(1)=3 and f(3)=6)
 (from the table f(1)=3 and f(3)=6)
Therefore h(1)=6
Now to find h'(1)
Let
 (since
 (since   )
 )
put x=1 in above function we get

 (From the table
    (From the table  and
 and  )
)

Therefore
