How do you subtract 20 mins. 45 seconds from one half hour?
Convert 20 minutes into seconds (20 * 60). There are sixty seconds in a minute. This would make 1200 seconds. Then add the 45 seconds (1245). Convert 30 minutes (1/2 an hour) into seconds (30 * 60). Then subtract 1245 from 1800. This would leave 555 seconds or 9 minutes, 15 seconds. I hope this helps.
What is 2 thirds of 1 hour 45 minutes?
To find two-thirds of 1 hour and 45 minutes, first convert 1 hour 45 minutes to a single unit, which is 105 minutes. Then, calculate two-thirds of 105 minutes by multiplying 105 by 2/3. This gives you 70 minutes, which can be further broken down as 1 hour and 10 minutes. Therefore, two-thirds of 1 hour and 45 minutes is 1 hour and 10 minutes.
What is faster kilometers per hour or meters per minute?
1 meter per minute is only 60 meters per hour, but 1 kilometer per hour is 16-2/3 meter per minute. So any number of kilometers per hour is 16-2/3 times as fast as the same number of meters per minute.
How do you turn 2 hours and 45 minutes into a mixed number?
So 45 minutes is 3/4 of an hour (60 minutes in an hour, 45/60 simplifies to 3/4). That means the mixed number would be 2 3/4 hours.
What is the ratio of 45 minutes to 2 hours?
45 minutes to 2 hours is the same as 45 minutes to 120 minutes. This can be reduced to 9/24, or 9 to 24.
