30 minutes
2 hours and 40 minutes. Since she was so massive, it took longer than most ships to sink
90
30 days : 49 days or 30:49
you multiply it by 52 and then simplify it.
This would be 30 watthours, or 0.030 kilowatthours
To calculate the number of minutes in 30 days, multiply the number of minutes in an hour (60) by the number of hours in a day (24) and then multiply that result by the number of days (30). Therefore, 60 (minutes per hour) x 24 (hours per day) x 30 (days) = 43,200 minutes in 30 days.
You can write 2.5 hours. This is the same as 25/10 hours. 1/10 of an hour is 6 minutes so 5/10 is 30 minutes. 2.5 hours is the same as writing 2hours 30 minutes. 3.75 hours = 3 hours 45 minutes 1.25 hours = 1 hour 15 minutes etc etc
Multiply it by 60 to find how many seconds there are.
2hours and 30 min
Convert the minutes to seconds (multiply them by 60), then divide the result by 30. Alternately, you can first convert seconds to minutes, then divide the equivalents in minutes.
There are: 30 times 60 = 1800 minutes
