An airplane 30,100 feet above the ground begins descending at the rae of 2,150 feet per minute. Write and solve a linear equation to find how long it will take the plane to reach the ground. (Use y=mx+b)
------------------
h(t) = 30100 - 2150t, h in feet, t in minutes
------------
At the ground, h= 0
30100 - 2150t = 0
30100 = 2150t
t = 30100/2150
t = 14 minutes
------------------
