  1. 4:37 · The hour hand hasn't reached 5 yet, so the hour is still 4. The minute hand shows how many minutes past.
  2. 3:57 · The hour hand hasn't reached 4 yet, so the hour is still 3. The minute hand gives you the minutes.
  3. 2 minutes · Brushing your teeth is a short job. A couple of minutes is enough, not hours and not just seconds.
  4. 7:42 · The hour hand is close to 8 but has not passed it yet, so the hour is still 7. The minute hand points to 42.
  5. Team B · To compare, put both times in the same unit: minutes.
  6. 120 · Change everything into minutes first, then add.
  7. 17 · Split the trip into two easy chunks: the time up to 9:00, then the time after 9:00.
  8. The movie · 45 minutes is more than 12 minutes, so the movie lasted longer.
  9. The song · The video lasted 14 minutes (2:48 to 3:02), but the song lasted 19 minutes (3:00 to 3:19), so the song was longer.
  10. She only added 10 minutes instead of 20 · 9:15 plus 20 minutes is 9:35. Zara only counted 10 minutes, so her end time is 10 minutes too early.
