<PRE><B>Question 1101580</B>
A jet cruising at 870 km/hr climbs at an angle of (15 degrees 30 minutes). What is its given altitude in 4 min?
--------------
870 km/hr * (4/60) hr = 58 kms (the hypotenuse)
Vertical distance = 58 km * sin(15.5)
=~ 15.5 km higher than when the climb began.
==================
PS
Planes use knots for speed, and feet for altitude.
Climbing is not cruising.
