Question 1180486
.
Two hikers leave on the same place at the same time and travels in opposite direction, one travels 2 km/h faster than
the other. If they are 168 {{{highlight(cross(km/h))}}} <U>kilometers</U> apart after 4 hours, form an equation representing the total distance covered by the hikers
after 4 hours. (using 1 variable)
~~~~~~~~~~~~~~~



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For your info: &nbsp;the unit for distance is &nbsp;<U>kilometers</U>


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It is not &nbsp;km/h, &nbsp;as you mistakenly wrote in your post.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;km/h &nbsp;is the unit for the rate or for the speed, &nbsp;but not for the distance.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;THEREFORE, I corrected your post accordingly.



<pre>
This equation is


    4x + 4*(x+2) = 168  kilometers.


Here x is the rate of the slower traveler.
</pre>

Solved, &nbsp;answered, &nbsp;explained, &nbsp;and all your errors are kindly fixed.
