Question

Из двух городов на встречу друг другу вышли 2 грузовика.Скорость 1 - 50,6км/ч , а 2 - на 7,6км/ч больше. Чему ровно расстояние между городами,если грузовики встретились через 0,5 часа?

Answer 1

1)50,6+7,6=58,2(км/ч)скорость второго грузовика, 2)50,6+58,2=108,8(км/ч)скорость сближения, 3) 108,8*0,5=54,4(км)расстояние между городами

Answer 2

T=0,5 ч.
V=$V_{1}$+$V_{2}$
$V_{1}$=50,6 (км/ч)
$V_{2}$=50,6+7,6= 58,2 (км/ч)
V = 50,6+58,2=108,8 (км/ч)
S = V*t
S = 108,8*0,5 = 54,4 (км)
Ответ: расстояние между городами 54,4 км

Answer 3

Problem Analysis

We have two trucks traveling towards each other from two different cities. The speed of the first truck is 50.6 km/h, while the speed of the second truck is 7.6 km/h faster. The trucks meet after 0.5 hours. We need to find the distance between the two cities.

Solution

Let's assume the distance between the two cities is d km.

The first truck travels at a speed of 50.6 km/h, so in 0.5 hours, it covers a distance of 50.6 * 0.5 = 25.3 km.

The second truck travels at a speed of 50.6 + 7.6 = 58.2 km/h, so in 0.5 hours, it covers a distance of 58.2 * 0.5 = 29.1 km.

Since the trucks are traveling towards each other, the sum of the distances covered by both trucks should be equal to the distance between the two cities.

Therefore, we can write the equation: 25.3 + 29.1 = d.

Simplifying the equation, we find that the distance between the two cities is 54.4 km.

Answer

The distance between the two cities is 54.4 km.
