Question

Помогите решить задачу: из Цветочного и Солнечного городов ,расстояние между которыми ровно 136 км, выехали одновременно навстречу друг другу Винтик и Шпунтик. Винтик двигался со скоростью 16 км/ч .С какой скоростью ехал Шпунтик,если они встретились через 4 ч после выезда?

Answer 1

16*4=64 столько проехал винтик
136-64=72 столько проехал шпунтик
72/4=18. Такова скорость Шпунтика
Ответ:18 км/час

Answer 2

Problem Analysis

We are given that the distance between the Flower City and the Sunny City is exactly 136 km. Vintik and Shpuntik started traveling towards each other at the same time. Vintik was moving at a speed of 16 km/h. We need to find the speed at which Shpuntik was traveling if they met after 4 hours.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's assume that Shpuntik's speed is x km/h. Since Vintik and Shpuntik are traveling towards each other, their combined speed is the sum of their individual speeds.

According to the problem, the distance between the two cities is 136 km, and they meet after 4 hours. Therefore, we can set up the following equation:

16 km/h + x km/h = 136 km / 4 hours

Now, let's solve this equation to find the value of x.

Calculation

To solve the equation, we can simplify it by multiplying both sides by 4:

16 km/h + x km/h = 34 km/h

Now, subtract 16 km/h from both sides:

x km/h = 34 km/h - 16 km/h

Simplifying further:

x km/h = 18 km/h

Answer

Therefore, Shpuntik was traveling at a speed of 18 km/h.
