Morphology
The meaning is directly derivable from combining 'light' (the phenomenon that travels) with 'minute' (a unit of time): it denotes how far light travels in one minute, following the same compositional pattern as 'light-year' or 'light-second'. This is a transparent, cross-linguistically regular way to form distance units based on the speed of light, so a B1 learner who knows both words can reasonably infer the intended meaning.
Etymology
Light minute comes from a simple image: imagine how far light travels in one minute. So when people say something is 'a light minute' away, they mean the distance light (or a signal) needs one minute to travel, which explains delays in messages from space.
