Question

Из двух пунктов расстояние между которыми равно 260 километров на встречу друг другу одновременно выехали два автомобиля сколько км скорость одного автомобиля равна 8 километров час а скорость второго 60 км в час какое расстояние будет между автомобилем и через 2,5 часов после начала двидени

Answer 1

Сначала нужно найти скорость сближения 8+60=68км\ч

потом 68*2=136км проехали за 2 часа
и 260-136=124кмрасстояние межде ними через 2 часа также найти и через пять

Answer 2

Problem Analysis

We are given that two cars start simultaneously from two points that are 260 kilometers apart. The first car has a speed of 8 kilometers per hour, while the second car has a speed of 60 kilometers per hour. We need to find the distance between the cars after 2.5 hours.

Solution

To find the distance between the cars after 2.5 hours, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by each car after 2.5 hours.

The first car travels at a speed of 8 kilometers per hour for 2.5 hours. Therefore, the distance traveled by the first car is:

Distance1 = 8 km/h × 2.5 h

The second car travels at a speed of 60 kilometers per hour for 2.5 hours. Therefore, the distance traveled by the second car is:

Distance2 = 60 km/h × 2.5 h

To find the distance between the cars after 2.5 hours, we subtract the distance traveled by the first car from the distance traveled by the second car:

Distance between the cars = Distance2 - Distance1

Let's calculate the distances:

Distance1 = 8 km/h × 2.5 h = 20 km

Distance2 = 60 km/h × 2.5 h = 150 km

Distance between the cars = 150 km - 20 km = 130 km

Therefore, the distance between the two cars after 2.5 hours will be 130 kilometers.

Answer

The distance between the two cars after 2.5 hours will be 130 kilometers.
