Question

At that rate, how many minutes will it

Answer 1

Answer:

It would require 12 minutes for the plane's attitude to change by -5,400 meters.

Step-by-step explanation:

As the altitude (or height) of a plane landing at an airport-changes at a rate of -450 meters per minute.

∴ unit rate = -450 meters/per minute

We have to determine how many  will it  take for the plane's altitude to change  by -5,400 meters.

• Altitude change per minute = -450 meters

i.e.

-450 × 1 = -450 meters    (altitude change in 1 minute)

so

-450 × 12 = - 5400 meters  (∴ unit rate = -450 meters/per minute)

At this rate, it would require 12 minutes for the plane's attitude to change by -5,400 meters.

Because -450 × 12 = - 5400 meters

Therefore, it would require 12 minutes for the plane's attitude to change by -5,400 meters.
