8 min

Respuesta :

Answer8 or 17 but i bbelive  its 8

Answer:

8 minutes

Step-by-step explanation:

Given:

  • Initial altitude = 14,000 ft
  • Cruising altitude = 38,000 ft
  • Rate of ascent = 3,000 ft min⁻¹

[tex]\boxed{\sf Time=\dfrac{Distance}{Speed}}[/tex]

Substitute the given values into the formula and solve for time:

[tex]\begin{aligned}\implies \sf Time & = \sf \dfrac{(38000-14000) \: ft}{3000\:ft\:min^{-1}}\\\\& = \sf \dfrac{24000}{3000\:min^{-1}}\\\\& = \sf \dfrac{24\:min}{3}\\\\& = \sf 8\:min\end{aligned}[/tex]

Therefore, it will take 8 minutes to reach cruising altitude.
