60 seconds an 1 minute 60 minutes in 1 hour 30 minutes in half an hour 90 minutes in one and a half hours. So 90 minutes * 60 seconds = 5400 seconds
3.5 minutes = 60 + 60 + 60 + 30 = 210 seconds.
lets use an example. you are told you have half of a minute. you know there are 60 seconds in a minute. therefore half of 60 is? 60/2 (x1) If you are told you have 3/12 of a minute. 60/12, x3 is 15 seconds.
43200 seconds / 60 seconds in a minute / 60 minutes in an hour = 12 otherwise known as half a day
Acvtually it's quite easy to work out. 19 is half of 38, so what is half of 60?
30 seconds in half a minute (there are 60 seconds in a minute)
There are 86,400 seconds in a day (24 hours x 60 minutes x 60 seconds). Therefore, in a day and a half (36 hours), there would be 129,600 seconds (36 hours x 60 minutes x 60 seconds).
30 minutes × 60 seconds = 1800 seconds in half an hour.
60 seconds an 1 minute 60 minutes in 1 hour 30 minutes in half an hour 90 minutes in one and a half hours. So 90 minutes * 60 seconds = 5400 seconds
There are no minutes in half a minute. - In one minute there are 60 seconds. - In half a minute there are 30 seconds. - In one hour there are 60 minutes. - In half an hour there are 30 minutes.
3.5 minutes = 60 + 60 + 60 + 30 = 210 seconds.
4.5 × 60 = 270 seconds.
lets use an example. you are told you have half of a minute. you know there are 60 seconds in a minute. therefore half of 60 is? 60/2 (x1) If you are told you have 3/12 of a minute. 60/12, x3 is 15 seconds.
30 seconds is half a minute (0.5 minutes), as there are 60 seconds in a full minute.
2.5 × 60 = 150 seconds
There are: 90*60 = 5,400 seconds
43200 seconds / 60 seconds in a minute / 60 minutes in an hour = 12 otherwise known as half a day
