Answer 1

75*3=225км путь 1 машины
52*3=156км путь 2 машины
225+156=381км расстояние между городами

Answer 2

Problem Analysis

We have two cars traveling towards each other from two different cities. The speed of one car is 75 km/h, and the speed of the other car is 52 km/h. After 3 hours, the cars meet. We need to find the distance each car traveled before the meeting and the distance between the two cities.

Solution

To find the distance each car traveled before the meeting, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by each car:

Car 1: - Speed: 75 km/h - Time: 3 hours - Distance = 75 km/h × 3 hours = 225 km

Car 2: - Speed: 52 km/h - Time: 3 hours - Distance = 52 km/h × 3 hours = 156 km

Therefore, each car traveled 225 km and 156 km, respectively, before the meeting.

To find the distance between the two cities, we can add the distances traveled by both cars:

Distance between the two cities = Distance traveled by Car 1 + Distance traveled by Car 2 = 225 km + 156 km = 381 km

So, each car traveled 225 km and 156 km before the meeting, and the distance between the two cities is 381 km.

Answer

Each car traveled 225 km and 156 km before the meeting, and the distance between the two cities is 381 km.
