An airplane 30,000 feet above the ground begins descending at the rate of 2000 feet per minute.
Assume the plane continues at the same rate of descent.
:
A)Write an equation to represent the height of an airplane (H) as it descends for (m) minutes.
H = 30000 - 2000m
:
B) Graph the situation.
:
C) What does the slope represent?
Slope can be defined as rise/run, this is a negative rise, -2000/1
:
D) What does the y-intercept represent?
30000 ft when the plane starts to descend, m=0
:
E) How long will it take for the airplane to reach 13,000 feet?
30000-2000m = 13000
-2000m = 13000 - 30000
-2000m = -17000
m = -17000/-2000
m = +8.5 min
:
green line represents 13000 ft
