4. I assume this is a serious question.
The calculations is as follows:
plane flies 410 km / hour
this equates to 410,000 meters per hour
this equates to 6,833.333... meters per minute
in order to fly 230KM, or 230,000 meters will thus take 33.65854.... minutes (or 2019.512 seconds)
since the plane increase altitute at a rate of 420 feet per minute, this means that in 33.65854 minutes, it would have reached 14,136.58537 feet.
Assume the measure of a 1 foot is according to the itnernational standard as defined in 1959 then the plane will be 4,308.83122 meters higher than what the point of origin. However, should you have opted for the Utrecth Foot measurement instead, then the plane would only be 3,856.460488meters higher. The funny one is that should you opted for the Bordeaux foot measurement, then the plane would be 5,049.786205 meters higher.
WOW AWESOME

woohooooo...
Distance = Speed x Time
so,
Time = Distance / Speed
substituting known values of Distance = 230 KM and Speed = 410KMH,
Time = 230 KM / 410kmh
therefore Time in hours is
Time = 0.56 hours (this is rounded but you need to keep the numbers in your calculator)
So Time in minutes is:
Time = 0.56 x 60 = 33.6 minutes
Distance = Speed x Time
Here the Distance is the altitude and the speed is the rate of climbing.
Substituting rate of 420 feet per minute and time of 33.6 minutes
Distance = 420 x 33.6
Distance = 14137.20 feet.
So the altitude of the plane would be 14137.20 feet.
Well done Skouperd
