Question

Из двух городов навстречу друг другу выехали два автомобиля. скорость одного 65км/ч,скорость другого на 10 км/ч больше. какова длина пути между городами,если через 3 часа длина пути между автомобилями была 435км. Спасибо!

Answer 1

65 + 10 = 75  км.-Скорость второго автомобиля 
 65 * 3 = 195 км.-проехал первый за 3 часа
 75 * 3 = 225 км-проехал второй за 3 часа
 195 + 225 = 420 км.-проехали вместе
 420 + 435 = 855 км.-растояние между городами

Answer 2

Скорость второго автомобиля 65 + 10 = 75 
За три часа проехали: первый 65 * 3 = 195 км; второй 75 * 3 = 225 км. Вместе 195 + 225 = 420 км. И осталось между ними 435 км. Расстояние между городами 420 + 435 = 855 км.

Answer 3

Problem Analysis

We have two cars traveling towards each other. The speed of one car is 65 km/h, and the speed of the other car is 10 km/h faster. After 3 hours, the distance between the 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 = 65 km/h * 3 hours = 195 km Distance traveled by the second car = 75 km/h * 3 hours = 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 Total distance = 195 km + 225 km Total distance = 420 km

Therefore, the length of the path between the two cities is 420 km.

Answer

The length of the path between the two cities is 420 km.
