№603 (с. 168)
Условие. №603 (с. 168)
скриншот условия
603 Расстояние от A до B равно 110 км. На путь из пункта A в пункт B автомобиль затратил $1\frac{2}{3}$ ч, а на обратный путь — на 10 мин больше. Определите скорость автомобиля в каждом направлении.
Решение 2. №603 (с. 168)
Скорость автомобиля из пункта А в пункт В
Для начала определим скорость автомобиля на пути из пункта А в пункт В. Нам известны расстояние и время в пути.
Расстояние (S) равно 110 км.
Время в пути ($t_1$) равно $1\frac{2}{3}$ часа.
Переведем время в неправильную дробь для удобства расчетов:
$t_1 = 1\frac{2}{3} = \frac{1 \cdot 3 + 2}{3} = \frac{5}{3}$ ч.
Скорость ($v$) вычисляется по формуле $v = \frac{S}{t}$.
Подставим наши значения:
$v_1 = \frac{110}{\frac{5}{3}} = 110 \cdot \frac{3}{5} = \frac{110 \cdot 3}{5} = 22 \cdot 3 = 66$ км/ч.
Ответ: 66 км/ч.
Скорость автомобиля из пункта В в пункт А
Теперь определим скорость на обратном пути. Расстояние осталось тем же (110 км), но время изменилось.
На обратный путь было затрачено на 10 минут больше. Сначала переведем 10 минут в часы:
$10$ мин $= \frac{10}{60}$ ч $= \frac{1}{6}$ ч.
Теперь найдем общее время на обратный путь ($t_2$), прибавив это значение ко времени пути из А в В:
$t_2 = t_1 + \frac{1}{6} = \frac{5}{3} + \frac{1}{6}$.
Приведем дроби к общему знаменателю 6:
$t_2 = \frac{5 \cdot 2}{3 \cdot 2} + \frac{1}{6} = \frac{10}{6} + \frac{1}{6} = \frac{11}{6}$ ч.
Теперь вычислим скорость на обратном пути ($v_2$):
$v_2 = \frac{S}{t_2} = \frac{110}{\frac{11}{6}} = 110 \cdot \frac{6}{11} = \frac{110 \cdot 6}{11} = 10 \cdot 6 = 60$ км/ч.
Ответ: 60 км/ч.
