22. Красный автомобиль проехал 144 км за 2 ч, а синий автомобиль проехал 300 м за 20 с. Скорость какого автомобиля больше? Во сколько раз?

Решение. №22 (с. 25)

Дано:

Красный автомобиль: $s_1 = 144$ км, $t_1 = 2$ ч

Синий автомобиль: $s_2 = 300$ м, $t_2 = 20$ с

Перевод в систему СИ:

$s_1 = 144 \text{ км} = 144 \cdot 1000 = 144000 \text{ м}$

$t_1 = 2 \text{ ч} = 2 \cdot 3600 = 7200 \text{ с}$

$s_2 = 300 \text{ м}$

$t_2 = 20 \text{ с}$

Найти:

Сравнить скорости автомобилей ($v_1$ и $v_2$) и найти, во сколько раз большая скорость превосходит меньшую.

Решение:

Для решения задачи необходимо найти скорости обоих автомобилей в одинаковых единицах измерения. Удобнее всего перевести все данные в Международную систему единиц (СИ) и вычислить скорости в метрах в секунду (м/с). Скорость равномерного движения вычисляется по формуле:

$v = \frac{s}{t}$

где $\text{v}$ — скорость, $\text{s}$ — пройденный путь, а $\text{t}$ — время в пути.

Вычислим скорость красного автомобиля ($v_1$), используя данные в системе СИ:

$v_1 = \frac{s_1}{t_1} = \frac{144000 \text{ м}}{7200 \text{ с}} = 20 \text{ м/с}$

Вычислим скорость синего автомобиля ($v_2$):

$v_2 = \frac{s_2}{t_2} = \frac{300 \text{ м}}{20 \text{ с}} = 15 \text{ м/с}$

Теперь, когда обе скорости выражены в м/с, мы можем их сравнить. Так как $20 \text{ м/с} > 15 \text{ м/с}$, то скорость красного автомобиля больше, чем скорость синего автомобиля.

Чтобы найти, во сколько раз скорость красного автомобиля больше, найдем отношение большей скорости к меньшей:

$\frac{v_1}{v_2} = \frac{20}{15} = \frac{4}{3} \approx 1,33$

Ответ: Скорость красного автомобиля больше. Скорость красного автомобиля больше скорости синего в $\frac{4}{3}$ раза (или приблизительно в 1,33 раза).
