Chapter at a Glance
- A second is a very small piece of time. Say one thousand one out loud — that takes about one second. Blinking your eyes takes less than a second. The thin red hand on a wall clock is the seconds hand. It is the fastest hand: it goes right round the dial in one minute.
- 60 seconds make 1 minute. 60 minutes make 1 hour. This is the one fact the whole chapter rests on. Watch the seconds hand: after it has ticked 60 little marks it has gone once round, and the minute hand has moved on by exactly one mark. So 1 min = 60 s and 1 hr = 60 min.
- Time is counted in sixties, not in tens. In money, 10 tens make 100. In time, it is 60 that makes the next unit. So when seconds add up past 60, we carry 1 to the minutes. 40 s + 35 s = 75 s = 1 min 15 s. And when we cannot subtract, we borrow 1 minute and it becomes 60 seconds, not 10.
- Reading a clock with three hands. Look at the short thick hand first — that is the hour hand; the number it has just passed is the hour. Then the long hand — the minute hand; count the small marks from 12 in fives. Then the thin hand — the seconds hand; count the small marks from 12 in fives again. A clock showing hour hand between 5 and 6, minute hand on 7 and seconds hand on 12 reads 5:35 and 0 seconds.
- The 12-hour way and the 24-hour way. A day has 24 hours, but a clock face has only 12 numbers. So the same 12 numbers are used twice — once for a.m. (midnight to noon) and once for p.m. (noon to midnight). Railways and airports do not use a.m. and p.m. at all. They count straight on from 00 to 23. Rule: an a.m. time stays the same; for a p.m. time add 12 to the hour. So 05:30 p.m. = 05:30 + 12:00 = 17:30 hours.
- Changing hours into minutes: multiply by 60. 3 hours = 3 × 60 = 180 minutes. To change minutes back into hours, divide by 60: 180 ÷ 60 = 3 hours. A leftover is written as minutes: 220 ÷ 60 gives 3 with 40 left over, so 220 min = 3 hours 40 minutes.
- Changing minutes into seconds: multiply by 60 again. 5 min = 5 × 60 = 300 seconds. And back the other way, divide by 60: 320 ÷ 60 gives 5 with 20 left over, so 320 s = 5 min 20 s.
- Finding how long something took. Do not start with a subtraction sum. Start at the earlier time and jump forward in easy hops — first whole hours, then the extra minutes. From 08:00 to 09:00 is one hop of 1 hour; from 09:00 to 09:05 is another hop of 5 minutes. Total 1 hour 5 minutes. Adding a duration works the same way, only forwards.
- Which unit — seconds or minutes? Ask yourself: could I count it while holding my breath? Snapping your fingers, blinking, sitting down — seconds. Melting an ice cube, making a phone call — minutes. Choosing the right unit is part of measuring well.
