Answer:
The answer is 8 miles
Step-by-step explanation:
Let the original trail be x
From the question 150% of the trail is
12 mile
That's
150% of x = 12
So we have
[tex] \frac{150}{100} x = 12 \\ \\ \frac{3}{2} x = 12[/tex]
Multiply through by 2
That's
[tex]2 \times \frac{3}{2} x = 12 \times 2[/tex]
We have
3x = 24
Divide both sides by 3
We have the final answer as
x = 8
Therefore the length of the original trail is
8 miles
