Answer 1

Ответ:

Пошаговое объяснение:

9-00 - 7-30=1час 30мин утром

15-15 -13-30= 1 час 45мин в обед

1-45+ 1-45+1-30=5 часов провел на тренировке

Answer 2

9-00 - 7-30 = таңертең 1 сағат 30 мин

15-15 -13-30 = түскі ас кезінде 1 сағат 45 минут

1-45 + 1-45 + 1-30 = жаттығуға жұмсалған 5 сағат

Problem Analysis

To solve this problem, we need to calculate the total time Rostik spent on training. We are given the start and end times of each training session. We'll calculate the duration of each session and then sum them up to find the total training time.

Calculation

Let's calculate the duration of each training session:

1. Morning training: Started at 7:30 AM and ended at 9:00 AM. The duration is 1 hour and 30 minutes. 2. Afternoon training: Started at 1:30 PM and ended at 3:15 PM. The duration is 1 hour and 45 minutes. 3. Evening training: Started at 9:00 PM and ended at 10:45 PM. The duration is 1 hour and 45 minutes.

Now, let's add up the durations of all the training sessions:

1 hour 30 minutes + 1 hour 45 minutes + 1 hour 45 minutes = 5 hours

Therefore, Rostik spent a total of 5 hours on training.

Answer

Rostik spent a total of 5 hours on training.
