What is the span of the range 40 to 200 inches of water?

Explanation:
Span is the distance between the smallest and largest values in a range. For 40 to 200 inches, subtract the smaller from the larger: 200 − 40 = 160 inches. So the interval length is 160 inches of water. The endpoints define the span, not their sum or average, which is why 160 is correct.
