Answer:
0.25 feet per minute
Step-by-step explanation:
Gravel is being dumped from a conveyor belt at a rate of 20 ft3/min. Since we are told that the shape formed is a cone, the rate of change of the volume of the cone.
Since base diameter = Height of the Cone
Radius of the Cone = h/2
Therefore,
Therefore: 
We want to determine how fast is the height of the pile is increasing when the pile is 10 feet high.

Answer:
10+12.50h=5+15h
We move all terms to the left:
10+12.50h-(5+15h)=0
We add all the numbers together, and all the variables
12.50h-(15h+5)+10=0
We get rid of parentheses
12.50h-15h-5+10=0
We add all the numbers together, and all the variables
-2.5h+5=0
We move all terms containing h to the left, all other terms to the right
-2.5h=-5
h=-5/-2.5
h=+2
