How long it takes on the clockLesson 226 of the lessons course of Mova's primary school: 3 sentences, each with its syntax tree and pragmatics. The lessons are written for Mova, and their agreed trees are part of Mova corpus 0.4 (CC BY-SA 4.0).0To find how long something lasts, count on from the start time to the next o'clock, then on to the end time.1An hour has 60 minutes, so from a quarter past to the next o'clock is 60 − 15 = 45 minutes.2From 3:45 to 4:30: 15 minutes to 4:00, then 30 more, so 15 + 30 = 45 minutes.← previousHours, minutes and secondsnext →Every day for a week↑ back to LessonsThis page in Markdown → https://md.mova.elamur.ai/free/en/corpora/school/lessons/226-how-long-on-the-clock/
