Question

Из городов одновременно выехали два грузовика. Расстояния между ними 600 км, скорость первого-54 км, 2-на 8 меньше.Через сколько часов они встретятся ?

Answer 1

54 - 8 = 46 км/ч - скорость второго грузовика
54 + 46 = 100 км/ч - скорость сближения
600 : 100 = 6 ч - через столько часов они встретятся

Answer 2

54-8= 46 скорость второго54+46=100 км/ч общая скорость600:100= 6 часов встретятся

Answer 3

Problem Analysis

Two trucks are simultaneously leaving from different cities. The distance between them is 600 km. The speed of the first truck is 54 km/h, and the speed of the second truck is 8 km/h less than the first truck. We need to calculate how many hours it will take for the trucks to meet.

Solution

Let's assume that it takes y hours for the trucks to meet. During this time, the first truck will travel a distance of 54y km, and the second truck will travel a distance of (54 - 8)y km.

Since the total distance between the trucks is 600 km, we can set up the following equation:

54y + (54 - 8)y = 600

Simplifying the equation:

62y = 600

Now, we can solve for y:

y = 600 / 62

Evaluating the expression:

y ≈ 9.68

Therefore, it will take approximately 9.68 hours for the trucks to meet.

Answer

The two trucks will meet after approximately 9.68 hours.

Explanation

When solving the problem, we set up an equation based on the distances traveled by each truck and the total distance between them. By solving the equation, we found that it will take approximately 9.68 hours for the trucks to meet.
