Question

1323. Автобус проходит расстояние от города до села за 1,8 ч, а легко- вая автомашина — за 0,8 ч. Найдите скорость автобуса, если известно, что она меньше скорости легковой автомашины на 50 км/ч. 1324. На первую автомашину погрузили на 0.6 т зерна больше, чем на

Answer 1

Объяснение:Пусть скорость автобуса х км ч . Тогда скорость автомашины х+ 50 км ч. Всё расстояние равно 1.8х или 0.8 (х+50) км. 1.8х=0.8 (х+ 50)

1.8х=0.8х+4

1х=4

Ответ:4км ч

Answer 2

Ответ:40

1323.

х - машина

0,8х=1,8х - 90

х = 90

90-50 = 40 км/ч

Answer 3

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, knowing 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. Since the bus is 50 km/h slower than the car, the speed of the bus is x - 50 km/h.

We can use the formula speed = distance / time to find the speed of each vehicle.

The distance traveled by both the bus and the car is the same, so we can set up the following equation:

distance / time_bus = distance / time_car

Simplifying the equation, we get:

distance / 1.8 = distance / 0.8

Cross-multiplying, we get:

0.8 * distance = 1.8 * distance

Simplifying further, we get:

0.8 * distance - 1.8 * distance = 0

Combining like terms, we get:

-1 * distance = 0

Since the distance cannot be zero, this equation has no solution.

Therefore, there is an error in the problem statement or the given information.

Please double-check the problem statement or provide additional information if available.
