Question

A group of aliens set on a journey from point A to point B, 1500 km apart, of a planet
by a super-jet. Considering the planet has an atmosphere, the scheduled flying time is
2 hours and 30 min travelling against the direction of the wind. It is known that with
every 100 feet increase in altitude, the speed of the wind increases by 10 kmph. The
super-jet covered the first half of the distance at an altitude of 30600 feet and the
wind speed was 900 kmph, 200 kmph quicker than what they had accounted for. If
the aliens manage to keep up to the schedule by flying at a lower altitude, then the
altitude at which the super-jet flew for the rest of its journey was?​
