PLZZZ GIVING BRAINLIST

Answer:
[tex] \dfrac{-7600}{3} [/tex]
Step-by-step explanation:
The plane is descending, so the change in height is a negative change.
rate of descent = (change in height)/time
rate of descent = (new height - old height)/time
rate of descent = (7400 ft - 15000 ft)/(3 min)
rate of descent = (-7600 ft)/(3 min)
