Question

Машина ехала до остановки 4 часа со скоростью 74 километров в час после этого ей осталось проехать в два раза меньше расстояние на которое ей понадобилось 2 часа с какой скоростью Ехала машина после остановки

Answer 1

1) 4 • 74 = 296 ( км )
2) 296 : 2 = 148 ( км )
3) 148 : 2 = 74 ( км/час )
Ответ 74 км/час

Answer 2

Problem Analysis

We are given that a car traveled for 4 hours at a speed of 74 kilometers per hour. After that, it had to travel half the distance it took to cover in 2 hours. We need to find the speed at which the car traveled after the stop.

Solution

Let's break down the problem step by step:

1. The car traveled for 4 hours at a speed of 74 kilometers per hour. Therefore, the distance covered during this time is 74 km/h × 4 h = 296 km.

2. The car had to travel half the distance it took to cover in 2 hours. Let's denote this distance as d. Therefore, the equation becomes: d = (296 km) / 2 = 148 km.

3. Now, we need to find the speed at which the car traveled after the stop. Let's denote this speed as x km/h.

4. We can use the formula speed = distance / time to find the speed. In this case, the distance is 148 km and the time is 2 hours. Therefore, the equation becomes: x = 148 km / 2 h = 74 km/h.

Answer

The car traveled at a speed of 74 kilometers per hour after the stop.

Verification

Let's verify the answer using the given information:

- The car traveled for 4 hours at a speed of 74 kilometers per hour, covering a distance of 296 km. - After the stop, it had to travel half the distance it took to cover in 2 hours, which is 148 km. - The speed at which the car traveled after the stop is calculated as 148 km / 2 h = 74 km/h.

The answer matches the given information, so it is correct.
