At what altitude does the plane fly if the atmospheric pressure at the surface of the earth

At what altitude does the plane fly if the atmospheric pressure at the surface of the earth was 750 millimeters of mercury and 450 mm outside the plane

We accept the value of the change in atmospheric pressure by 1 mm Hg. with an increase in height of 10 meters.

We find the difference in pressure at the surface of the earth and at the height.

In this case, we get:

750 – 450 = 300 mm Hg

We find the flight altitude of the aircraft.

To do this, multiply the pressure difference by a constant height value of 10 meters.

We get:

300 * 10 = 3000 meters.

Answer:

The plane flies at an altitude of 3000 meters.
