Since the rate is 22.5, just multiply by 2.5 and you get 56.25, subtract that and the answer is 3.75 miles from the destination.
DE and EF are segments of the line DF, so they will add up to DF. This can be represented with this equation:
Combine like terms:
Add 15 to both sides:
Subtract 6x from both sides:
Divide both sides by 3 to get x by itself:
The value of x will be 8.
Plug this value of x into the expression for DF:
DF will equal 57.

Answer:
85
Step-by-step explanation:
Given data
Abby test scores 95, 82, 78, 88
We see that the number of test
n is 4
Hence the average test score is
Average score = ∑scores/n
Average score = 95+82+78+88/4
Average score = 343/4= 85.75
≈ the average test score is 85
