Question

Помогите пожалуйста решить !!Автобус проходит расстояние от города до села за 1,8 ч,а легковая автомашина - за 0,8 ч. Найдите скорость автобуса ,если известно,что она меньше скорости легковой автомашины на 50 км/ч.

Answer 1

Пусть х скорость легковой машины,тогда
Х-50 скорость автобуса
0,8х путь легковой машины
1,8(х-50). Путь автобуса
Т.к.путь один и тот же,составим уравнение:
0,8х=1,8(х-50)
0,8х-1,8х=-90
Х=90км/ч скорость легковой
90-50=40км/ч скорость автобуса

Answer 2

Problem Analysis

We are given that a bus travels a distance from a city to a village in 1.8 hours, while a car travels the same distance in 0.8 hours. We need to find the speed of the bus, given that it is 50 km/h slower than the speed of the car.

Solution

Let's assume the speed of the car is x km/h. According to the given information, the speed of the bus is 50 km/h slower than the speed of the car, so the speed of the bus can be represented as (x - 50) km/h.

To find the speed of the bus, we can use the formula:

Speed = Distance / Time

Since the distance is the same for both the bus and the car, we can set up the following equation:

(x - 50) = Distance / 1.8

Simplifying the equation, we get:

x - 50 = Distance / 1.8

To solve for x, we need to know the value of the distance. Unfortunately, the distance is not provided in the given information. Without the distance, we cannot calculate the speed of the bus accurately.

Please provide the distance between the city and the village so that we can calculate the speed of the bus.
