Calculating the Time Difference

To calculate the difference in time spent by Kostya and Vitya on training the dog to track game, we can use the given information. Kostya spent two sessions of 45 minutes each, while Vitya spent two sessions of 20 minutes each.

Step 1: Calculate the total time spent by Kostya and Vitya. - Kostya: 2 sessions * 45 minutes/session = 90 minutes - Vitya: 2 sessions * 20 minutes/session = 40 minutes

Step 2: Find the difference in time spent. - Difference = Time spent by Kostya - Time spent by Vitya - Difference = 90 minutes - 40 minutes - Difference = 50 minutes

Therefore, Kostya spent 50 minutes longer training the dog to track game than Vitya.
