Question

A submarine is 150 below sea level while in airplane is 375 above sea level. What is the difference between the height of the seven marine and the airplane

Answer 1

Answer: 525

Explanation:

The submarine is 150 BELOW sea level. Hence, considering sea level as 0 as we go down below the height becomes - 150.

In contrast, the airplane is above so it's +375

To find the difference, subtract it

375-(-150) {two minus become positive}

= 375+150

525 units

Answer 2

525 feet.

Explanation:

Difference in height

= 375 - (-150) Remembering that - * - = + :-

= 375 + 150

= 525 feet.
