Answer 1

1) 11-8=3 (ч) - время в пути.

2) 70+60=150 (км/ч) - общая скорость или скорость сближения.

3)  150

Answer 3

Problem Analysis

We have two cars that start from two different cities and meet each other after 3 hours. We need to find the distance between the cities given that one car is traveling at a speed of 60 km/h and the other car is traveling at a speed of 70 km/h.

Solution

To find the distance between the cities, we can use the formula:

Distance = Speed × Time

Let's calculate the distance using this formula.

Calculation

Car 1 is traveling at a speed of 60 km/h and Car 2 is traveling at a speed of 70 km/h. They meet after 3 hours.

The distance traveled by Car 1 is: Distance1 = Speed1 × Time = 60 km/h × 3 hours = 180 km.

The distance traveled by Car 2 is: Distance2 = Speed2 × Time = 70 km/h × 3 hours = 210 km.

Since the two cars meet each other, the sum of their distances should be equal to the total distance between the cities.

Total Distance = Distance1 + Distance2 = 180 km + 210 km = 390 km

Therefore, the distance between the two cities is 390 km.

Answer

The distance between the two cities is 390 km.
