Tempoh

Latihan bola jaring bermula pada pukul 3:10 petang dan tamat pada pukul 3:48 petang.
Berapa lamakah latihan itu?

Tempoh
时长 = tempoh 时长就是从开始到结束一共经过了多少时间。可以看钟面数分钟,可以在时间线上一段一段地跳,也可以用结束时间减去开始时间。跨过中午的时候,先把时间改成 24 小时制再减,比较不容易错。 例子:从 2:00 到 2:30,经过 30 分钟。 注意:一小时等于六十分钟,借位时借来的是 60,不是 100。
duration = tempoh Duration is how much time passes from the start to the end. You can count minutes on a clock face, jump along a time line, or subtract the start time from the end time. When the time crosses noon, first change both times to the 24-hour system. Example: from 2:00 to 2:30, 30 minutes pass. Watch out: 1 hour = 60 minutes, so a borrow gives 60, not 100.
Dalam minit

Kira minit pada muka jam

3:10 petang hingga 3:48 petang

48 − 10 = 38 minit
用钟面数分钟 = kira pada muka jam 开始和结束都在三点多,只有分针在动:分针从十分走到四十八分,涂色的部分就是经过的时间。四十八减十得三十八,所以练习了三十八分钟。 例子:从 5:05 到 5:40 → 35 分钟。 注意:同一个小时里才能直接相减分钟。
count minutes on a clock face = kira pada muka jam Both times are after 3 o'clock, so only the minute hand moves: from 10 minutes past to 48 minutes past. The shaded part is the time that passed: 48 − 10 = 38 minutes. Example: from 5:05 to 5:40 is 35 minutes. Watch out: subtract the minutes directly only within the same hour.

Tempoh = 3 jam
整小时 = dalam jam 在时间线上从 Jam 0900 开始,每次跳一个小时:到 1000、到 1100、到 1200,一共跳了三次,所以一共经过三个小时。也可以直接用十二减九等于三。 例子:Jam 1300 到 Jam 1700 → 4 小时。 注意:分钟都是 00 时,只要比较小时。
whole hours = dalam jam On the time line start at Jam 0900 and jump one hour at a time: to 1000, 1100 and 1200. Three jumps make 3 hours. You can also subtract 12 − 9 = 3. Example: Jam 1300 to Jam 1700 is 4 hours. Watch out: when both minutes are 00, just compare the hours.
Jam dan minit

Dua cara

8:25 a.m. hingga 11:50 a.m.

8:2511:2511:503 jam25 minTempoh = 3 jam 25 minit
几小时几分钟 = jam dan minit 方法一:在时间线上先跳整小时,从 8:25 跳三个小时到 11:25,再跳二十五分钟到 11:50,一共三小时二十五分钟。方法二:把结束时间和开始时间写成小时和分钟两栏,分钟五十减二十五得二十五,小时十一减八得三。两种方法答案一样。 例子:7:05 到 9:50 → 2 小时 45 分钟。 注意:分钟和分钟减,小时和小时减。
hours and minutes = jam dan minit Method 1: on a time line jump whole hours first, 3 hours from 8:25 to 11:25, then 25 minutes to 11:50: 3 hours 25 minutes. Method 2: write the times in hours and minutes columns: 50 − 25 = 25 minutes and 11 − 8 = 3 hours. Both give the same answer. Example: 7:05 to 9:50 is 2 hours 45 minutes. Watch out: subtract minutes from minutes and hours from hours.
Melepasi tengah hari

Tukar kepada sistem 24 jam, kemudian tolak

8:45 pagi hingga 4:20 petang

8:459:004:004:2015 min7 jam20 minTempoh = 7 jam 35 minit
跨过中午 = melepasi tengah hari 下午 4:20 先改成 Jam 1620。分钟二十不够减四十五,向小时借一,一小时等于六十分钟,所以分钟变成八十,八十减四十五得三十五;小时十六借走一变十五,十五减八得七。方法一在时间线上也得到十五分钟、七小时、二十分钟,加起来七小时三十五分钟。 例子:10:30 a.m. 到 1:10 p.m. → 2 小时 40 分钟。 注意:借来的是六十分钟,不是一百。
crossing noon = melepasi tengah hari First write 4:20 p.m. as Jam 1620. 20 minutes is less than 45, so borrow 1 hour = 60 minutes: 80 − 45 = 35 minutes; the hours become 15, and 15 − 8 = 7. Method 1 on a time line gives 15 min + 7 hours + 20 min, also 7 hours 35 minutes. Example: 10:30 a.m. to 1:10 p.m. is 2 hours 40 minutes. Watch out: a borrowed hour is 60 minutes, not 100.

Berapakah tempoh dari 10:40 a.m. hingga 11:15 a.m.?

跨过整点的分钟 = melepasi pukul penuh 开始和结束不在同一个小时里,分钟不能直接相减。方法:分两段来数——先从开始时间数到下一个整点,再从整点数到结束时间,最后把两段分钟加起来。 例子:2:50 到 3:20 → 10 分钟 + 20 分钟 = 30 分钟。 注意:一小时只有六十分钟,不能当作一百分钟来计算。
minutes across the hour = melepasi pukul penuh The start and end are in different hours, so you cannot subtract the minutes directly. Count in two parts: from the start time up to the next o'clock, then from that o'clock to the end time, and add the two parts. Example: 2:50 to 3:20 → 10 minutes + 20 minutes = 30 minutes. Watch out: an hour has only 60 minutes; never treat it as 100.

Berapakah tempoh dari Jam 0835 hingga Jam 1410?

借六十分钟 = tukar 1 jam kepada 60 minit 用竖式:结束时间写上面,开始时间写下面,分成小时和分钟两栏。先减分钟:如果上面的分钟不够减,就从小时借一,一小时换成六十分钟加到分钟栏,小时栏少一,然后再减小时。 例子:Jam 1205 − Jam 0950:5 分钟不够减 50,借一小时变 65,65 − 50 = 15;小时 11 − 9 = 2 → 2 小时 15 分钟。 注意:借位后小时那一栏要少 1;相减得到的分钟一定小于 60。
borrow 60 minutes = tukar 1 jam kepada 60 minit Write the end time on top and the start time below, in hours and minutes columns. Subtract the minutes first; if the top minutes are too small, change 1 hour into 60 minutes, add them to the minutes column and take 1 from the hours, then subtract the hours. Example: Jam 1205 − Jam 0950: 5 is less than 50, so borrow to make 65; 65 − 50 = 15 and 11 − 9 = 2 → 2 hours 15 minutes. Watch out: after borrowing, the hours column is 1 less, and the minutes in the answer are always below 60.
Ringkasan

Syabas!

tamat − mula

Tempoh = waktu tamat − waktu mula. 1 jam = 60 minit.
