Let x be the distance of the additional water stations from the starting line.
We want on that is 1.5 miles behind the 8-mile water station, and one that is 1.5 miles ahead. The following absolute value function describes x:
|x-1.5| = 8
Two numbers comply: x= 9.5 and 6.5.
The additional water stations will be 6.5 and 9.5 miles from the starting line.

Option A: >
Solution:
Given a triangle GHJ.
The line GH is perpendicular to line HJ.
This means the triangle is a right angled triangle.
In ΔGHJ, GH is the base of the triangle and
HJ is a height of the triangle.
Then the third side must be the hypotenuse of the right triangle.
We know that by the Pythagoras theorem,


This clearly shows that the hypotenuse is greater than the height.
⇒ GJ > HJ
Option A: > is the correct answer.
If line GH is perpendicular to line HJ, then GJ is > HJ.
4800/15.80(per/h) = 303.8 hours / 20 hours per week = 15.19 weeks.
The slope of the equation is calculated as:

Where
is the height of the upper part of the slope and
is the height of the low er part.


So, the equation of the line is:


With this equation we can find the height of Alberto after having passed 10 sec.

After 10 seconds Alberto is 350 feet from the bottom of the slope.
Alberto's speed is:

The speed in miles per hour is:
