Она успевает только на две электрички в 9:45 и в 9:58. Смотрим, какая из них раньше приедет в Клин, очевидно, что та, что выйдет из Москвы в 9:58.
Вычитаем из 10:54 - 9:58 = 2 минуты +54минуты = 56 минут

электричка 6412 отбывает в 09:58, а прибывает в 10:54 - приходит на 28 минут раньше, чем электричка 6618
