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

Ok so set up a proportion:
now cross multiply to get
50x = 900
divide 50 on both sides
x = 900/50 = 18 mi
now cross multiply to get
50x = 900
divide 50 on both sides
x = 900/50 = 18 mi
