Question

Из двух городов навстречу друг другу выехали два автомобиля. скорость первого автомобиля 65 км ч скорость второго на 10 км ч больше .какова длина пути между городами если через 3 ч длина пути между автомобилями была 435 км‽

Answer 1

1) 65+10=75( км/ч) скорость второго авто
2) (65+75)*3=420 (км) пройдут 2 автомобиля за 3 часа
3) 420+435=855(км) расстояние между городами
 Ответ: 855 километров.
1)65+10=75(км/ч)-скорость второго автомобиля
2)(65+75)*3=420(км)-прошли 2 автомобиля
3)420+435=855(км)
Ответ:855 км.

Answer 2

Problem Analysis

Two cars are traveling towards each other from two different cities. The speed of the first car is 65 km/h, and the speed of the second car is 10 km/h faster than the first car. After 3 hours, the distance between the two cars is 435 km. We need to find the total distance between the two cities.

Solution

Let's assume the speed of the second car is x km/h. Since the speed of the second car is 10 km/h faster than the first car, we can write the equation:

x = 65 + 10

Simplifying the equation, we find:

x = 75

Now, we can calculate the distance traveled by each car in 3 hours:

Distance traveled by the first car = Speed of the first car * Time = 65 km/h * 3 h = 195 km Distance traveled by the second car = Speed of the second car * Time = 75 km/h * 3 h = 225 km

The total distance between the two cities is the sum of the distances traveled by each car:

Total distance = Distance traveled by the first car + Distance traveled by the second car = 195 km + 225 km = 420 km

Therefore, the total distance between the two cities is 420 km.

Answer

The total distance between the two cities is 420 km.
