Step-by-step explanation:
Any point on a given parabola is equidistant from focus and directrix.
Given:
Focus of the parabola is at .
Directrix of the parabola is .
Let be any point on the parabola. Then, from the definition of a parabola,
Distance of from focus = Distance of
from directrix.
Therefore,
Squaring both sides, we get
Hence, the equation of the parabola is .
Step-by-step explanation:
To solve this problem, let's set up our equation to solve for x (time to travel 13 miles).
We use this equation to find x. To solve, we divide 13 by 65 to get our answer.
13 ÷ 65 = 0.2
Our answer: 0.2 hours
