It s now 10:15 and half an hour later, how much time?

Half an hour is 30 minutes, and 10:15 plus 30 minutes is 10:45. So the time is 10:45.

It's now 10:15 and half an hour later, and it's 10:45The calculation process is 10:15 + 0:30 = 10:45. Every 60 minutes is 1 hour.

It's now 10:15 and half an hour, which is 10:45 minutes, and according to the fact that half an hour is equal to 30 minutes, you can get 15+30 equals 45 minutes.

The time is 10:45.

Half an hour is 30 minutes, and 15 minutes + 30 minutes equals 45 minutes, which is less than an hour, so the result is 10:45.

It's 10:15 a.m., and it's 10:45 a.m. in half an hour. 15 points plus 30 points equals 45 points, and half an hour means 30 points.

Solution: The time is in the 60 decimal system, half an hour = 30 minutes, according to the question.

A: The time is 10:45.

10:15+30 minutes 10:45 a.m., and another half hour at 10:45 a.m.

Half an hour is just 30 minutes, 10:15 + 30 = 10:45, which is equal to 10:45.

It's now 10:15, and in half an hour, it's 10:45

If your time is 10:15, what is the next half hour?

That's 10:15 + 30 minutes, which is equal to 10:45. Because half an hour is 30 minutes. You will see it at a glance.

If it's 10:15 a.m., and half an hour is 10:45, and another half hour is 10:15 plus 30 points, and 15 plus 30 points equals 45 points, so another half an hour is 10:45.

1 hour from 11:30 to 12:30. There are several ways to calculate time:

1. Hours. It is generally the cut-off time minus the start time. For example, from 1 o'clock to 10 o'clock, the middle is 10-1 = 9 hours.

2. Number of days. Generally, it is the cut-off time minus the beginning of the time width notice plus 1. Be cautious for example. No. 1 to No. 10 is 10 days, if 10-1=9, there are only 9 days, but there are actually 10 days, so add 1.

3. The number of months and years should be calculated in the same way as the number of days.

Time Unit Conversion:

Century 100 years;

Year 12 months;

Month 30 days;

Day 24 hours;

Hours: 60 minutes;

min 60 sec;

sec 1000 ms;

Milliseconds 1000 microseconds.

9. Youtan 1 microsecond 1000 nanoseconds;

1000 picoseconds per nanosecond.

The big month (31 days) has: 1 3 5 7 8 10 December.

Moon. 30 days) are: 4 6 9 November.

28 days in February in ordinary years and 29 days in February in leap years.

There are 365 days in a normal year and 366 days in a leap year.

This question seems relatively simple, but there are actually two answers: 1 hour, 13 hours.

In the first case, according to the correct timekeeping, 10:30 is recorded as 10:30, and 11:30 is recorded as 11:30, then the elapsed time is: 11:30-10:30 = 1 hour.

The second scenario: 10:30 a.m. during the day and 11:30 p.m. This time period should be:

23:30-10:30=13 hours.

There is also a situation from 10:30 p.m. to 11:30 a.m. the next day, which is also 13 hours).

What time is 1 o'clock after 10 o'clock in the world, we can use the number banquet which return to the banquet to learn the expression column, that is, 1:00 + 10:00 = 11:00, so 1 o'clock after 10 hours is 11 o'clock.

Summary. Hello classmates, half an hour is equal to 30 minutes, so 15:10 + 30 minutes is equal to 15:40. So the answer is 15:40.

Hello classmates, half an hour is equal to 30 minutes, so 15:10 + 30 minutes is equal to 15:40. So the answer is 15:40.

From 15:10 to 15:40 is half an hour.

The end time and start time must be in 24 hours). 2. The time conversion relationship is as follows: 1 hour hr (h) = 60 minutes min (m) = 3600 sec (s).

3. Vertical calculation refers to a vertical calculation in the calculation process to make the calculation simple. The same digits are aligned during the addition calculation, and if the sum of the beats exceeds 10, it will advance by 1. The same digits are aligned when subtracting, if it is not enough to subtract, then borrow 1 as 10 from the previous digit and hope that mine can help you.

Hello, so 15:10 to 15:40 is half an hour.

For example, from 1-8 there are holes in the withered shouting of several intervals defeated group. Using (8-1) = 7 is in line with reality. And so on. 15:30-11:30=4。Nano so has 4 hours.

Solution: 15:10+1:00=16:10

A: An hour after 15:10 is 16:10.

An hour after 15:10 is 16:10.

A: 10:25-11:00 = 35 minutes, 35 60 = 7 12 hours. Because 1 hour is equal to 60 minutes.

Because there are 24 hours in a day, how many hours are from 11:20 to 1:30, we can use the column of mathematical expressions to express which kernel: 1:30-11:

Slow skating 20 + 24:00 = 14:10, so there are 14 hours and 10 minutes from 11:20 to 1:30.
