Form an inequality for a distance d meters which is more than 18m, but not more than 23m
18 ≤ d ≤ 23
18 < d ≤ 23
18 ≤ d < 23
d < 18 or d > 23
Explanation
more than means greater than WHILE not more than means less than or equal to
therefore the answer is 18 < d ≤ 23 meaning d is more than 8 but can be equal to or less than 23
