A hot air balloon is 20 feet above the ground and is rising at a rate of 15 feet per minute. Another balloon is 150 feet above the ground and is descending at a rate of 20 feet per minute. At what height will the balloons be the same distance from the ground?
---------------------------------
Equation:
Let x be the time required to get the objects to the same height.
--------------------
20+15x = 150-20x
-----
35x = 130
x = 3.714 minutes
