59000ft-10000ft=49000ft
49000ft/3500(ft/min)=14minutes

Answer:

14 minutes.

Step-by-step explanation:

We have been a commercial jet has been instructed to climb from its present altitude of 10,000 feet to a cruising altitude of 59,000 ft.

First of all, we will find change in altitude.

[tex]\text{Change in altitude}=59,000-10,000=49,000[/tex]

To find the time taken by a plane to reach 59,000 ft, we will divide change in altitude by 3,500.

[tex]\text{Required time}=\frac{49,000\text{ ft}}{\frac{3,500\text{ ft}}{\text{min}}}[/tex]

[tex]\text{Required time}=\frac{49,000\text{ ft}}{3,500}\times \frac{\text{ min}}{\text{ ft}}[/tex]

[tex]\text{Required time}=14\text{ min}[/tex]

Therefore, it will take 14 minutes for the plane to reach its cruising altitude.
