Answer:
h(t) = 40,000 - 1,500t
Step-by-step explanation:
Let h(t) be the height of the airplane after t minutes.
h(t) = 40,000 - 1,500t
8/15 = 56/105
This may be solved using proportion.
a/b = c/d
ad = bc where cross products are equal.
a = 8
b = f
c = 56
d = 105
ad = bc
8*105 = f*56
840 = 56f
840/56 = 56f/56
f = 15
56 ÷ 7 = 8
105 ÷ 7 = 15
Differentiate the given solution:
Substitute 
and 
into the ODE:
and it's easy to see the left side indeed reduces to 0.
