Question

Из двух городов одновременно навстречу друг другу вышли два грузовика.Скорость первого-50,6км/ч, а скорость второго-на 7,6км/ч больше.Чему равно расстояние между этими городами, если грузовики встретились через 0,5ч?

Answer 1

1) 50,6+7,6=58,6 км/ч - скорость 2-го грузовика
2) 50,6+58,6=109,2 км/ч - скорость сближения
3) 109,2·0,5=54,6 км - расстояние между городами

Answer 2

Problem Analysis

We are given that two trucks start from two different cities and travel towards each other. The speed of the first truck is 50.6 km/h, while the speed of the second truck is 7.6 km/h faster. We need to find the distance between the two cities when the trucks meet after 0.5 hours.

Solution

Let's denote the speed of the second truck as x km/h. Since the speed of the second truck is 7.6 km/h faster than the first truck, we can write the equation:

x = 50.6 + 7.6

Simplifying the equation, we find:

x = 58.2

Now, we can calculate the distance traveled by each truck using the formula:

distance = speed × time

For the first truck, the distance traveled is:

distance1 = 50.6 × 0.5

And for the second truck, the distance traveled is:

distance2 = 58.2 × 0.5

The total distance between the two cities is the sum of the distances traveled by each truck:

total distance = distance1 + distance2

Let's calculate the total distance.

Calculation

Using the given values, we can calculate the total distance:

distance1 = 50.6 × 0.5 = 25.3 km

distance2 = 58.2 × 0.5 = 29.1 km

total distance = distance1 + distance2 = 25.3 + 29.1 = 54.4 km

Therefore, the distance between the two cities is 54.4 km.

Answer

The distance between the two cities, when the trucks meet after 0.5 hours, is 54.4 km.
