Question 426561
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/sin(17)}}}, 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.
