Question

Когда турист проехал 3/8 всего пути между двумя городами, то до половины пути ему осталось проехать 15 км. Найдите расстояние между городами. Дайте ответ в километрах.

Answer 1

Половина это 4/8
4/8 - 3/8 = 1/8 = 15км
15 х 8 = 120км
ответ: 120 км

Answer 2

Problem Analysis

We are given that a tourist has traveled 3/8 of the total distance between two cities and has 15 km remaining to reach the halfway point. We need to find the distance between the two cities.

Solution

Let's assume the total distance between the two cities is represented by d km.

According to the given information, the tourist has traveled 3/8 of the total distance, which is equal to (3/8) * d km.

The remaining distance to reach the halfway point is 15 km.

To find the total distance between the two cities, we can set up the following equation:

(3/8) * d + 15 = (1/2) * d

Simplifying the equation:

(3/8) * d + 15 = (1/2) * d

Multiplying both sides of the equation by 8 to eliminate the fraction:

3d + 120 = 4d

Subtracting 3d from both sides of the equation:

120 = d

Therefore, the distance between the two cities is 120 km.

Answer

The distance between the two cities is 120 km.
