The higher up in the atmosphere you are, the thinner the air and therefore the less the drag on the plane. Thus if both planes' engines are under the same power (using the same amount of fuel) the plane at the higher altitude will have a faster airspeed.
As altitude increases (to about 35,000 ft) air density, pressure and temperature all drop. As density decreases speed of sound increases, but with drop in pressure it drops; these two practically cancel each other out. As temperature drops, speed of sound drops. Thus at 15,000 ft the speed of sound is slower than at 6,000 ft so plane X is flying faster than plane Y.

The higher you are from the Earth's surface - the lower the air pressure is. Helicopters are heavy machines - requiring a huge amount of effort from the rotor blades to keep it airborn. The lower the air-pressure, the harder the rotors have to work to keep the craft flying.
The airplane was flying at a very high altitude.
Altitude shows the height from earth. when Aeroplanes flying in the sky, Pilot announces we are flying at an altitude of 30,000 feet.Altitude is your height above sea level.

A Piper Cub can cover 500 miles in the same amount of time it takes a jet plane flying 250 miles per hour faster to cover 1500 miles. Piper Cub is flying 125 mph.
