Morphology

an + hour + and + a + half

The meaning is directly compositional: 'hour' (60 minutes) plus 'and a half' (an additional half of an hour) yields 90 minutes, so a learner who knows 'hour' and 'half' can compute the duration. The 'X and a half' construction is a regular, cross-linguistic way to indicate one-and-a-half units, making this immediately understandable to a B1 learner.

Etymology

The phrase an hour and a half is a simple clock picture: an hour is 60 minutes and a half is 30 minutes. Put them together and you have 90 minutes, so the phrase means '90 minutes'.
