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  kilometers apart after 4 hours, form an equation representing the total distance covered by the hikers
after 4 hours. (using 1 variable)
~~~~~~~~~~~~~~~
For your info: the unit for distance is kilometers
It is not km/h, as you mistakenly wrote in your post.
km/h is the unit for the rate or for the speed, but not for the distance.
THEREFORE, I corrected your post accordingly.
This equation is
4x + 4*(x+2) = 168 kilometers.
Here x is the rate of the slower traveler.
Solved, answered, explained, and all your errors are kindly fixed.
