At this point of the Earth's surface, the Stratosphere layer is at most at 50 km, and at least at 16 km altitude.

If y represents a height which is in the Stratosphere layer, then we know that y is at least 16 km, which is represented by $16 \leq y$ ,

and y is at most 50 km, which is represented by $y \leq 50$ .

Combining these 2 inequalities we have:

$16 \leq y \leq 50$ , where y is in km
