Let
t = time, hours
h = height, feet
At 1 PM, the time and height are respectively
t₁ = 1 hour
h₁ = 4400 feet
At 4 PM, the time and height are respectively
t₂ = 4 hours
h₂ = 5600 feet
By definition, the mean hourly change in elevation is

Answer: 400 feet per hour
Step-by-step explanation:
a=110
b=110
c=70
d=70
e=110
f=70
g=110
2x-7+-6x-3 2x+-6x=-4x
-4x-10=0
-5/2 is the answer
