Question

Mt. Everest, the highest elevation in Asia, is 29,028 feet above sea level. The Dead Sea, the lowest elevation, is 1,312 feet below sea level. What is the difference between these two elevations? Show your work

Answer 1

Answer:

29,028 - 1312 = 27716 is the difference between elevations .

Step-by-step explanation:

Answer 2

Answer:

30,340 feet above sea level is the correct answer.

Step-by-step explanation:

To find the difference to between the two sea levels, subtract the lowest quantity (or the elevation of the Dead Sea) to the largest quantity (or the elevation of Mt. Everest.)

However, in this situation, you must also add the quantity of the above sea level to the subtraction, since the lower quantity is above sea level.

29,028 - 29,028 = 0

Now, we must subtract the lower quantity of 1,312.

0 - 1,312 = -1,312

If this was to be represented on a number line, the difference between our work relates to the absolute value, or the amount of spaces a number is from 0. Even though this is a negative number, you can take away the sign (if there is any) from in front of the number, and the absolute value will still be 1,312.

To find the total difference, add 29,028 to 1,312.

29,028 + 1,312 = 30,340

Therefore, our final answer is 30,340 feet above sea level.

Hope this helps! :)
