Subject: is there any performance difference between Range#include? and Range#cover?

I used once `cover?` and again `include?`. Both are looking same as per
functionality. But is there any advantages one over the other? or both
are same?

**********************************************
ranges =[(1..10), (60..80), (200..400)]

numbers = [123, 700, 567]
numbers.any?{|x| ranges.any? {|y| y.include? x}} #=> false

numbers = [123, 400, 567]
numbers.any?{|x| ranges.any? {|y| y.include? x}} #=> true
**********************************************
ranges =[(1..10), (60..80), (200..400)]

numbers = [123, 700, 567]
numbers.any?{|x| ranges.any? {|y| y.cover? x}} #=> false

numbers = [123, 400, 567]
numbers.any?{|x| ranges.any? {|y| y.cover? x}} #=> true
