Answer 1

75 км/ч. |> 80 км/ч.
|_______________________|
t=4
S=?
1) 80+75=155(км/ч) общая скорость
2) 155×4=620(км)
Ответ: на расстоянии 620 км будут два автомобиля.

Answer 2

80*4=320
75*4=300
320+300=620

Они будут друг от друга на расстоянии 620км

Answer 3

Problem Analysis

We have two cars traveling in opposite directions. The speed of one car is 80 km/h, and the speed of the other car is 75 km/h. We need to find the distance between the two cars after 4 hours.

Solution

To solve this problem, we can use the formula:

Distance = Speed x Time

Let's calculate the distance traveled by each car after 4 hours.

Car 1: Speed = 80 km/h Time = 4 hours

Distance1 = 80 km/h x 4 hours

Car 2: Speed = 75 km/h Time = 4 hours

Distance2 = 75 km/h x 4 hours

To find the distance between the two cars, we can subtract the distance traveled by one car from the distance traveled by the other car.

Distance between the two cars = Distance1 - Distance2

Let's calculate the distances and find the answer.

Calculation

Distance1 = 80 km/h x 4 hours = 320 km Distance2 = 75 km/h x 4 hours = 300 km

Distance between the two cars = 320 km - 300 km = 20 km

Answer

The two cars will be 20 km apart from each other after 4 hours.

Diagram

Here is a simple diagram to illustrate the situation:

Car 1: 80 km/h
          ----> 320 km
Car 2: 75 km/h
