Answer 1

1)74-8=66км/ч-2авт.
2)74×7=532км-прошёл 1авт.
3)66×7=462км-прошёл 2авт.
4)532+462=994км

Answer 2

Problem Analysis

We have two cars that start simultaneously from the same city in opposite directions. The speed of one car is 74 km/h, which is 8 km/h faster than the speed of the other car. We need to find the distance between them after 7 hours.

Solution

Let's break down the problem step by step:

1. We know that the speed of one car is 74 km/h, which is 8 km/h faster than the speed of the other car. Therefore, the speed of the other car is 74 km/h - 8 km/h = 66 km/h.

2. To find the distance traveled by each car after 7 hours, we can use the formula: distance = speed * time.

- The distance traveled by the car with a speed of 74 km/h is 74 km/h * 7 hours = 518 km. - The distance traveled by the car with a speed of 66 km/h is 66 km/h * 7 hours = 462 km.

3. Since the cars are moving in opposite directions, the total distance between them after 7 hours is the sum of the distances traveled by each car.

- Total distance = distance traveled by the first car + distance traveled by the second car - Total distance = 518 km + 462 km = 980 km.

Therefore, the distance between the two cars after 7 hours will be 980 km.

Answer

The distance between the two cars after 7 hours will be 980 km.
