Answer:
Over a 22 seconds, the altitude will be: 924 feet
Step-by-step explanation:
- Let 'x' be the time in seconds
As the altitude of an airplane is decreasing at a rate of 42 ft per second.
Thus, the expression to find the altitude at x seconds is:
y = 42x
so at x = 1 sec, y = 42 feet
Now, putting x = 22 seconds to determine the altitude at 22 seconds
y = 42x
= 42(22)
= 924 feet
Thus, over a 22 seconds, the altitude will be: 924 feet
