Answer:
k = 12
Step-by-step explanation:
Given:
The equation 
To find:
Value of
for which the given equation has one distinct real solution.
Solution:
The given equation is a quadratic equation.
There are always two solutions of a quadratic equation.
For the equation:
to have one distinct solution:

Here,
a = 2,
b = -k and
c = 18
Putting the values, we get:

The equation becomes:

And the one root is:

The answer is 4.5 miles. Hope it helps!
Multiply both sides by three to get 2x=30
Then divide both sides by 2 to get x=15
The answer is to your question is 100:1
