Question

A plane flies at an altitude of 5,000 ft and is descending at a rate of 100 ft per minute. Write an equation to represent the altitude of the plane.
a. A = 100m + 5000
b. A = 5000m + 100
c. A = 5000 – 100m
d. A = 5000 + 100

Answer 1

Answer:

correct answer

Step-by-step explanation:

option C

A=5000-100m is the correct answer

I know because I fly a plane in simulator

that's why I answer it

Answer 2

Answer:

C

Step-by-step explanation:

The 'm' stands for 'minute' and it helps us describe the change of altitude that takes place every minute.

The answer is 5000 - 100m. The answer cannot be B because the amount of decension that takes place is -100 feet every minute, not 5000 feet every minute. By placing the m infront of 5000, we are suggesting that that as every minute passes, the plane rises by 5000 feet with an addition of 100 feet, which is not the case as explained in the exercise.

The answer cannot be D as there is no time frame present in the equation and it would simply equate to a numeral value of 5100.

And neither can the answer be A because the plane is supposed to be descending -100 feet every minute, not rising 100 feet every minute. This answer would be correct if the 100m value was negative.
