A helicopter is flying at an altitude of 4,000 feet and starts descending at a rate of 100 feet per minute. What will be the altitude of the plane after 10 minutes?

it would be 40

Step-by-step explanation:

It would be 40 because you divide the 4000 feet by 100

like this

4000/100

then you divide it like its 40 divided by 10

thats how you get 40

3,000

Step-by-step explanation:

100 per minute: 100m

100x 10 =1,000

4,000-1,000= 3,000
