Объяснение:

Рас­смот­рим чертёж.

1) С одной сто­ро­ны ва­го­на че­ты­ре ко­ле­са. По­это­му в по­ез­де 48/4 = 12 ва­го­нов.

2) Длина ва­го­на при­мер­но равна 24,5 м. Вдоль всего со­ста­ва об­ход­чик про­хо­дит за 5 мин = 300 с. Зна­чит, длина по­ез­да при­мер­но равна 294 м, а сред­няя ско­рость об­ход­чи­ка при­мер­но равна 294 м / 300 с = 1 м/с.

3) Ми­ни­маль­ное рас­сто­я­ние между осями двух со­сед­них колёс равно 2,4 м. По­это­му ми­ни­маль­ный ин­тер­вал вре­ме­ни между слы­ши­мы­ми уда­ра­ми равен 2,4 м / 1 м/с = 2,4 с.
