2. Divide the number of seconds by 60 to convert seconds to minutes. Every 60 seconds a full minute has passed. Dividing a number tells you how many times one number fits in the other.
This decimal represents the number of seconds left over. For example, 90 seconds equals 1.5 minutes (90 / 60). This means that there is 1 minute plus an extra half of a minute (.5 of a minute) in 90 seconds. To convert this back to seconds, simply multiply the decimal by 60.Answer: There is 1 minute and 30 (.5 x 60) seconds in 90 seconds.ivide the number of minutes by 60 again to convert seconds to hours. There are also 60 minutes in an hour, so we use the same process, dividing by 60, to determine how many seconds are in an hour.
