Answer:

35000 - 2500m

Step-by-step explanation:

Height of the airplane before it starts descending = 35,000 feet

Rate of descend = 2500 feet per minute

This means for every 1 minute the height of airplane is decreasing by 2500 feet. So, for every "m" minutes the height of airplane will decrease by 2500m feet.

Let h(m) denotes the height of the airplane after m minutes. The equation for h(m) can be set up as:

Height of airplane at m'th minute = Original Height - Distance descended in m minutes

So,

h(m) = 35000 - 2500m

This expression describes the height of airplane after any number of minutes(m).
