Answer 1

To solve this problem, we can use the formula:

New Pressure = Original Pressure - (Original Pressure * Decrease Percentage)

Plugging in the given information:
Original Pressure = 104 kilopascals
Decrease Percentage = 11.3% = 0.113

Using the formula:
New Pressure = 104 - (104 * 0.113)
New Pressure = 104 - 11.752
New Pressure ≈ 92.248

Rounding the answer to the nearest whole number:
New Pressure ≈ 92 kilopascals

Therefore, the approximate pressure at an altitude of 2000 m is 92 kilopascals.
