Will she make it in time?
Literal
She [topic-は] in-time-make [I wonder-でしょうか]?
間に合う ('to make it in time / to be sufficient') is a high-frequency verb whose meaning ranges across both 'arrive on schedule' and 'be enough for the purpose' — the literal sense is 'meet the gap/interval.' でしょうか combines the conjectural でしょう with the question particle か, producing a softer, more formal interrogative than plain ~ますか. It's the question form used when expressing genuine uncertainty about an outcome you can't confirm — 'I wonder whether...' The intonation is rising, but the conjectural shading makes this feel more reflective than a sharp factual question.
