Question

Из 2 городов одновременно навстречу друг другу выехали 2 автомобиля и встретились через 3 часа скорость 1 80км в час это на 35км в час больше скорости 2 автомобиля найдите расстояние между городами

Answer 1

V1=180   V2=180+35=215    t=3   s=?
s=(V1+V2)*t=(180+215)*3=395*3=1185

Answer 2

Problem Analysis

We are given that two cars start simultaneously from two different cities and meet each other after 3 hours. The speed of the first car is 80 km/h, which is 35 km/h faster than the speed of the second car. We need to find the distance between the two cities.

Solution

Let's assume the speed of the second car is x km/h. Since the first car is traveling 35 km/h faster, its speed is x + 35 km/h.

We know that distance = speed × time.

For the first car, the distance it travels in 3 hours is (x + 35) × 3 km.

For the second car, the distance it travels in 3 hours is x × 3 km.

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

Therefore, we can write the equation:

(x + 35) × 3 + x × 3 = total distance

Simplifying the equation:

3x + 105 + 3x = total distance

6x + 105 = total distance

To find the total distance, we need to know the value of x. Let's solve for x.

6x + 105 = total distance

6x = total distance - 105

x = (total distance - 105) / 6

Now, we can substitute the value of x back into the equation to find the total distance.

total distance = (x + 35) × 3 + x × 3

total distance = (x + 35 + x) × 3

total distance = (2x + 35) × 3

total distance = 6x + 105

Substituting the value of x:

total distance = 6 * ((total distance - 105) / 6) + 105

Simplifying the equation:

total distance = total distance - 105 + 105

total distance = total distance

This means that the total distance between the two cities can be any value. The information provided in the question is not sufficient to determine the exact distance between the two cities.

Therefore, the distance between the two cities cannot be determined with the given information.

Answer

The distance between the two cities cannot be determined with the given information.
