shusha [124]

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
$\frac{h_{2} - h_{1}}{t_{2} - t_{1}} = \frac{5600-4400}{4-1} = \frac{1200}{3} =400$

Answer: 400 feet per hour
