Solution: Denote x feet the distance that must travel the plane to reach the altitude 13,000 feet.Since the sin(17)=13000/x we find:
x=13000%2Fsin%2817%29, x=49266 feet.
The time needed to travel this distance is: t=49,266/270=182.5 second.
Answer:The plane takes 3 min. and 2.5 sec. to reach 13000 feet altitude.
