Question 486206
1.3 <= h <= 1.5
This is a useful shorthand for the 2 contained inequalities.
Assume "each" means "this" and similar problems, each pair becomes a single absolute.  Otherwise it doesn't make much sense.
Find the midpoint of the interval, 1.4, and its distance to endpoints, 0.1.
|h - 1.4| <= 0.1
