Calculation of the End Time for the 5th Tennis Lesson

To calculate the end time for the 5th tennis lesson, we need to consider the duration of each lesson and the breaks between them.

According to the information provided, each tennis lesson in the sports school lasts for 45 minutes, and there is a 15-minute break between each lesson.

Let's calculate the time it takes for the first four lessons and the breaks:

- 1st lesson: 11:00 - 11:45 (45 minutes) - Break: 11:45 - 12:00 (15 minutes) - 2nd lesson: 12:00 - 12:45 (45 minutes) - Break: 12:45 - 13:00 (15 minutes) - 3rd lesson: 13:00 - 13:45 (45 minutes) - Break: 13:45 - 14:00 (15 minutes) - 4th lesson: 14:00 - 14:45 (45 minutes) - Break: 14:45 - 15:00 (15 minutes)

Now, let's calculate the start time of the 5th lesson. Since each lesson lasts for 45 minutes and there is a 15-minute break between each lesson, the start time of the 5th lesson would be:

- Start time of the 5th lesson: 15:00 + (45 minutes + 15 minutes) * 4

Let's calculate the start time of the 5th lesson:

- Start time of the 5th lesson: 15:00 + (45 + 15) * 4 - Start time of the 5th lesson: 15:00 + 60 * 4 - Start time of the 5th lesson: 15:00 + 240 - Start time of the 5th lesson: 19:00

Therefore, the 5th tennis lesson would start at 19:00.

Please note that the calculation assumes that each lesson and break are precisely timed and there are no additional delays or changes in the schedule.
