Morphology
The meaning 'very quickly' is directly derivable from combining 'double' (doubly/twice) with 'quick' (fast) as an intensifier meaning roughly 'twice as fast' or 'very fast'. This is a straightforward compositional intensifier + adjective pattern found in English and other languages, so a B1 learner who knows both constituents would likely infer the MWE's meaning.
Etymology
The phrase double quick comes from soldiers' marching orders: when an officer shouted the command double quick, the men changed from a normal step to a much faster run, with double and quick showing extra speed. That's why double quick now means 'very quickly'.
