Ответ:

4 год 10 хв

Пошаговое объяснение:

Щоб знайти середнє арифметичне, треба додати всі величини та поділити на їх кількість

Щоб було зручніше переведемо години в хвилини

3 год 52 хв + 4 год 20 хв + 4 год 18 хв = 232 хв + 260 хв + 258 хв = 750 хв

Тепер треба поділити отриману суму на 3, тому що в нас 3 числа

750 хв : 3 = 250 хв

Переведемо назад в години

250 хв = 4 год 10 хв
