Question

От заправочных станций, находящихся на некотором расстояний друг от друга, выехали одновременно в одном направлений два грузовика. Скорость первого грузовика -70км/ч,Скорость второго -60км/ч.Через 5часов первый грузовик догнал второй. Найдите расстояние между заправочными станциями.

Answer 1

1)70км/ч-60км/ч=10(км/ч)-скорость пиближения
2)10км/ч×5ч=10(км)-расстояние между заправками
Ответ:расстояние между заправками 10км

Answer 2

Problem Analysis

Two trucks start from different gas stations simultaneously and travel in the same direction. The first truck has a speed of 70 km/h, and the second truck has a speed of 60 km/h. After 5 hours, the first truck catches up to the second truck. We need to find the distance between the gas stations.

Solution

Let's assume that the distance between the gas stations is d km.

After 5 hours, the first truck has traveled a distance of 70 km/h * 5 h = 350 km. The second truck has traveled a distance of 60 km/h * 5 h = 300 km.

At this point, the first truck has caught up to the second truck, so the distance traveled by the second truck is equal to the distance between the gas stations minus the distance traveled by the first truck: 300 km = d km - 350 km.

To find the value of d, we can rearrange the equation: d km = 300 km + 350 km.

Now we can calculate the value of d: d km = 650 km.

Therefore, the distance between the gas stations is 650 km.

Answer

The distance between the gas stations is 650 km.
