Question

6. Из двух городов одновременно навстречу друг другу выехали два автомобиля. Один ехал со скоростью 50 км/ч, другой - — со скоростью 70 км/ч. На сколько километров больше проехал второй автомобиль до места их встречи, если расстояние между городами 600 км? Запишите решение и ответ

Answer 1

Ответ:

Первый автомобиль проехал 50 · 5 = 250 км. Второй автомобиль проехал 70 · 5 = 350 км. Следовательно, второй автомобиль проехал на 350 − 250 = 100 км больше, чем первый. Ответ: 100 км.

Answer 2

Ответ: 100 км
Объяснение: Удачи

Answer 3

Problem Analysis

Two cars are traveling towards each other from two different cities. The first car is traveling at a speed of 50 km/h, while the second car is traveling at a speed of 70 km/h. The distance between the cities is 600 km. We need to determine how many kilometers the second car traveled more than the first car before they met.

Solution

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

Let's assume that the first car traveled for t hours before they met. Therefore, the second car traveled for t hours as well.

The distance traveled by the first car can be calculated as: distance1 = speed1 × t.

The distance traveled by the second car can be calculated as: distance2 = speed2 × t.

Since the two cars are traveling towards each other, the sum of their distances should be equal to the total distance between the cities: distance1 + distance2 = 600.

Substituting the values, we get: 50t + 70t = 600.

Simplifying the equation, we have: 120t = 600.

Dividing both sides of the equation by 120, we find: t = 5.

Therefore, the first car traveled for 5 hours, and the second car also traveled for 5 hours.

To find the distance traveled by the second car, we can substitute the value of t into the equation for distance2: distance2 = 70 × 5 = 350.

Thus, the second car traveled 350 kilometers before they met.

Answer

The second car traveled 350 kilometers more than the first car before they met.
