Помогите решить задачу пожалуйста! Двое решают как им обойдётся дешевле доехать из Перми в Казань-на поезде или на автомобиле. Билет на поезд стоит 750 рублей на одного человека. Автомобиль расходует 6 литров бензина на 100 км пути, расстояние по шоссе равна 26 рублям за литр. Сколько рублей придётся заплатить за наиболее дешёвую поездку на двоих. Заранее спасибо!

Автор ответа: Ёжик801

1) 750 * 2 = 1500 (руб.) обойдётся им доехать из Перми в Казань на поезде.

2) 800 : 100 = 8 (раз) будет по 6 литров на 1 км.

3) 8 * 6 = 48 (л.) литров уйдёт на всю поездку.

4) 48 * 26 = 1248 (руб.) обойдётся им доехать из Перми в Казань на автомобиле.

5) 1248 < 1500

Ответ : наиболее дешёвая поездка из Перми в Казань будет на автомобиле.

Then we're going to visit some places with the
other exchange students. I think we're going to
go to Oxford on Tuesday and to Bath on Friday.
You must bring some warm clothes because
it often rains here in summer. There's a big
carnival in London at the weekend. We're going
to have fun!
