I would use 90 sec.
1 minute and 30 seconds is 1.5 minutes.
It is 30/60 or 1/2 simplified
1 minute and 30 seconds
it is 30
30 seconds in 1/2 minute.
gold 1 minute silver one minute 15 seconds bronze 1 minute 30 seconds
1 minute.
3:30 - 1:38 = 1:52 or 1 minute and 52 seconds or 112 seconds
The answer is 210 seconds because:Keyhalf a minute=30 sec Method:a minute=6o seconds 60x3= 180+30=2103.5 minutes * 60 = 210 seconds
To write one minute and a half in numerical form, you would express it as 1:30. This represents one minute (1) and thirty seconds (30) on a clock. In terms of fractions, you could also write it as 1 1/2 minutes, where the whole number represents the minute and the fraction represents the additional 30 seconds.
To solve this question we must first know that there are in fact 60 seconds in one minute. So to calculate the amount of seconds in 30 minutes we need to multiply 30 minutes by 60 seconds. 30 mins x 60 secs = 1800 seconds per 30 minutes of time.
1 hour = 100% 1 minute in an hour = 1/60 therefore 30 seconds in an hour = 1/120
