Question

Два автомобиля выехали одновременно навстречу друг другу из двух пунктов,расстояние между которыми 330км, и встретились через 2 часа.Найдите скорость каждого автомобиля, если скорость одного из них на 5 км/ч больше, чем скорость другого.

Answer 1

Скорость 1 автомобиля - Х км\ч , скорость 2 автомобиля - Х + 5 км\ч.
уравнение:
( х + х + 5 ) * 2 = 330
( 2х + 5 ) * 2 = 330
4х + 10 = 330
4х = 320
х = 80
Скорость 1 автомобиля - 80 км\ч, скорость 2 автомобиля - 85 км\ч.

Answer 2

Problem Analysis

We have two cars that start at the same time and travel towards each other from two different points. The distance between the two points is 330 km, and they meet after 2 hours. We need to find the speed of each car, given that one car's speed is 5 km/h faster than the other.

Solution

Let's assume the speed of the slower car is x km/h. Then the speed of the faster car will be x + 5 km/h.

We can use the formula speed = distance / time to find the speeds of the cars.

For the slower car: - Distance = 330 km (the total distance between the two points) - Time = 2 hours (the time it takes for the cars to meet)

For the faster car: - Distance = 330 km (the total distance between the two points) - Time = 2 hours (the time it takes for the cars to meet)

Let's calculate the speeds of the cars:

For the slower car: - Speed = Distance / Time = 330 km / 2 hours = 165 km/h

For the faster car: - Speed = Distance / Time = 330 km / 2 hours = 165 km/h

Therefore, the speed of each car is 165 km/h.

Answer

The speed of each car is 165 km/h.
