Answer 1

1)60+40=100(км/ч)
2)200:100=2(ч)
Ответ: Через 2 часа машины встретится

Answer 2

Problem Analysis

We are given that two cars start from different villages and are traveling towards each other. The distance between the villages is 200 km. One car is traveling at a speed of 60 km/h, while the other car is traveling at a speed of 40 km/h. We need to determine how many hours it will take for the cars to meet.

Solution

To solve this problem, we can use the formula:

Time = Distance / Speed

Let's calculate the time it takes for each car to travel the distance between the villages.

For the first car traveling at 60 km/h: Time1 = Distance / Speed1 = 200 km / 60 km/h

For the second car traveling at 40 km/h: Time2 = Distance / Speed2 = 200 km / 40 km/h

To find the total time it takes for the cars to meet, we can add the individual times together:

Total Time = Time1 + Time2

Let's calculate the total time.

Calculation

Using the given values:

Time1 = 200 km / 60 km/h = 3.33 hours

Time2 = 200 km / 40 km/h = 5 hours

Total Time = Time1 + Time2 = 3.33 hours + 5 hours = 8.33 hours

Therefore, it will take approximately 8.33 hours for the two cars to meet.

Answer

The two cars will meet after approximately 8.33 hours.
