Условие. №2 (с. 230)
скриншот условия
2 Кассы музея-заповедника начинают работать в 10:00. Папа попросил дочерей подсчитать, в котором часу они должны выехать из Великих Лук, чтобы подъехать к открытию касс. Он сказал им, что среднюю скорость движения автомобиля по трассе можно считать примерно равной 80 км/ч.
Решение. №2 (с. 230)
Решение 2. №2 (с. 230)
Для решения этой задачи необходимо знать расстояние от города Великие Луки до музея-заповедника, которое в условии не указано. Вероятно, это расстояние было дано в контексте предыдущих задач. Предположим, что расстояние составляет 120 км (например, до музея-заповедника «Михайловское»).
1. Найдём время, которое потребуется на дорогу.
Чтобы найти время ($t$), нужно расстояние ($S$) разделить на среднюю скорость ($v$).
Формула: $t = S / v$
Подставим известные значения, где $S = 120$ км и $v = 80$ км/ч:
$t = 120 \text{ км} / 80 \text{ км/ч} = 1,5$ часа.
2. Переведём полученное время в часы и минуты.
1,5 часа — это 1 час и 0,5 часа. В одном часе 60 минут, значит 0,5 часа — это половина часа.
$0,5 \times 60 = 30$ минут.
Таким образом, время в пути составит 1 час 30 минут.
3. Рассчитаем время выезда.
Кассы музея открываются в 10:00. Чтобы приехать точно к открытию, нужно выехать из Великих Лук за 1 час 30 минут до 10:00.
10 часов 00 минут – 1 час 30 минут = 8 часов 30 минут.
Ответ: они должны выехать из Великих Лук в 8:30.
