Tom descended 1500 feet in his airplane. He then ascended 2500 feet and remained at that altitude. If the initial altitude was 20,000 feet, what is Tom's altitude now?

Answer :

Final answer:

Tom's current altitude is 21,000 feet.

Explanation:

The subject of this problem is Mathematics, particularly, operations with numbers. The problem involves additive adjustment of altitude which corresponds to subtraction and addition. We start with Tom's initial altitude which is 20,000 feet. The problem tells us that Tom descended 1500 feet, which means we subtract 1500 from 20000. That gets us to 18500 feet. Then, Tom ascended 2500 feet, which means we add 2500 to the 18500. The final altitude after all these adjustments would be 21000 feet.

Tom's initial altitude was 20,000 feet. He descended 1,500 feet and then ascended 2,500 feet. To find Tom's current altitude, we need to subtract the distance he descended from the distance he ascended and add the result to his initial altitude.

Altitude = Initial Altitude + Ascent - Descent
Altitude = 20,000 + 2,500 - 1,500
Altitude = 21,000 feet

Tom's current altitude is 21,000 feet.

tom’s altitude is now 21,000 feet.

20,000 - 1,500 = 18,500
18,500 + 2,500 = 21,000
