Question 1124196
.
<pre>
Let "x" be  the time she will spend biking (in hours).

Then the time running is (x+2) hours.



The distance running is  6*(x+2)  (speed times time).

The distance biking  is  22*x     (speed times time).



Your equation is


    <U>Distanse</U> + <U>distance</U> = <U>total distance</U>,   or


    6*(x+2)  + 22x      = 85  miles.


Simplify and solve for x.


Then evaluate (x+2).
