Answer:

4000 feet

Explanation:

GIVEN: An airplane is flying at an elevation of
$3,750\text{ feet}$ and lands on an airstrip
$250\text{ feet}$ below sea level.

TO FIND: What is the difference between these two elevation.

SOLUTION:

Elevation of airplane while flying
$=3750\text{ feet}$

As airstrip is below sea level,

Elevation airplane while on airstrip
$=-250\text{ feet}$

Difference between elevations
$=\text{elevation when flying}-\text{elevations while on airstrip}$

=3750-(-250)

$=3750+250 \text{feet}$

$=4000\text{ feet}$

Hence difference between elevations is 4000 feet.
