One minute after take off, an airplane altitude was 4,000 feet. Three minutes later , it was 20,000 feet what was the planes average altitude change , in feet per minute, during those three minutes

Answer :

Answer:

The average altitude change of plane with time is 8,000 feet per min .

Step-by-step explanation:

Given as :

The initial height of plane after 1 min take off = 4,000 feet

The final height of plane after 3 min later = 20,000 feet

Let The rate of change of altitude in feet per min = s feet per min

Now, According to question

The change in altitude = final altitude - initial altitude

Or, D = 20,000 feet - 4,000 feet

I.e Distance change = 16,000 feet

The change in time = final time - initial time

Or T = 3 min - 1 min

I.e Time change = 2 min

Speed = [tex]\dfrac{\textrm Distance}{\textrm Time}[/tex]

So, s = [tex]\frac{16,000}{2}[/tex] feet per min

∴    s = 8,000 feet per min

So, Rate of change of altitude with respect to time = s = 8,000 feet per min

Hence The average altitude change of plane with time is 8,000 feet per min . Answer
