Problem Analysis

The problem states that Vitya, Kostya, and Lobzik were tracking a ground squirrel in the steppe. The tracking started at 9:15 AM and ended at 9:45 PM on the same day. We need to determine how much time Vitya, Kostya, and Lobzik spent tracking the squirrel.

Solution

To find the duration of the tracking, we need to subtract the start time from the end time. Let's break down the problem step by step:

1. Convert the start time of 9:15 AM to 24-hour format: 09:15. 2. Convert the end time of 9:45 PM to 24-hour format: 21:45. 3. Subtract the start time from the end time to find the duration.

Let's calculate the duration using the given start and end times.

Calculation

Start time: 09:15 (AM) End time: 21:45 (PM)

To calculate the duration, we subtract the start time from the end time:

21:45 - 09:15 = 12 hours and 30 minutes.

Therefore, Vitya, Kostya, and Lobzik spent 12 hours and 30 minutes tracking the squirrel in the steppe.
