Let’s check out your problem:

An airplane begins its descent to land from a height of 35,000 feet above sea level. The airplane's height changes by about -4000 feet every 3 minutes. Rounded to the nearest minute, in approximately how many minutes will the plane land? Assume that the airport runway is at sea level.

An airplane begins its descent to land from a height of 3535,000000 feet above sea level. The airplane's height changes by about 4000-4000 feet every 33 minutes. Rounded to the nearest minute, in approximately how many minutes will the plane land? Assume that the airport runway is at sea level.

Full solution

Q. An airplane begins its descent to land from a height of 3535,000000 feet above sea level. The airplane's height changes by about 4000-4000 feet every 33 minutes. Rounded to the nearest minute, in approximately how many minutes will the plane land? Assume that the airport runway is at sea level.
  1. Calculate Total Descent Distance: Determine the total distance the airplane needs to descend to reach sea level from 35,00035,000 feet.\newlineSince the airplane is at 35,00035,000 feet and needs to reach sea level, which is 00 feet, it needs to descend a total of 35,00035,000 feet.
  2. Calculate Rate of Descent: Calculate the rate of descent per minute. The airplane descends 4000-4000 feet every 33 minutes. To find the descent per minute, divide 4000-4000 feet by 33 minutes. 4000-4000 feet / 33 minutes = 1333.33-1333.33 feet per minute (rounded to two decimal places).
  3. Calculate Total Descent Time: Calculate the total time required for the airplane to descend 35,00035,000 feet at the rate of 1333.33-1333.33 feet per minute.\newlineTo find the time, divide the total distance to descend by the rate of descent per minute.\newline35,00035,000 feet // 1333.33-1333.33 feet per minute == 26.25-26.25 minutes.
  4. Take Absolute Value of Time: Since we cannot have a negative time, we take the absolute value of the time calculated in Step 33.\newlineAbsolute value of 26.25-26.25 minutes is 26.2526.25 minutes.
  5. Round Time to Nearest Minute: Round the time to the nearest minute. 26.2526.25 minutes rounded to the nearest minute is 2626 minutes.
