Sue is in an airplane which travels at a constant 300 kilometers per hour. The angle of climb of the airplane is 30
∘. How long (in seconds) would it take from takeoff,
before the airplane reaches 3000 meters, when Sue can access Wifi and work on the rest of the weekly problems?

the distance flown,
d = 3000/sin30° = 6000m
That's 6km, so it will take 6/300 = 1/50 hr = 72 seconds
