Question

из пунктф A и B, расстояние между которыми 260 км/ч, одновременно навстречу друг к другу выехали автобус и автомобиль. скорость автобуса- х км/ч, а скорость автомобиля-укм/ч (х меньше у). запишите в виде выражения:1 на сколько скорость автобуса меньше скорости автомобиля?2 во сколько раз скорость автобуса меньше скорости автомобиля?3 время, которое потребуется автобусу на весь путь из A в B?4 время, которое потребуется автомобилю на весь путь из A в B?5 на сколько меньше потребуется времиги на весь путь автомобилю, чем автобусу?6 во сколько раз меньше потребуется времини нп вемь путь автомобилю чем автобусу?7 скорость сближения автобуса и автомобиля?8 чере з какое время после начала движения автобус и автомобиль встретятся?

Answer 1

1)у-х

2)у/х

3)260/х

4)260/у

5)260/х-260/у

6)(260/х)/(260/4) только без скобок

7)х+у

8)260/(х+у)

Answer 2

Given Information:

- Distance between points A and B: 260 km/h - Speed of the bus: x km/h - Speed of the car: u km/h (where x < u)

Expressions to Calculate:

1. The difference in speed between the bus and the car. 2. The ratio of the bus's speed to the car's speed. 3. The time it will take for the bus to travel the entire distance from A to B. 4. The time it will take for the car to travel the entire distance from A to B. 5. The difference in time it will take for the car compared to the bus to travel the entire distance. 6. The ratio of the time it will take for the car to the time it will take for the bus to travel the entire distance. 7. The closing speed of the bus and the car. 8. The time it will take for the bus and the car to meet after the start of their journey.

Calculations:

1. The difference in speed between the bus and the car is given by u - x km/h. 2. The ratio of the bus's speed to the car's speed is given by x / u. 3. The time it will take for the bus to travel the entire distance from A to B is given by 260 / x hours. 4. The time it will take for the car to travel the entire distance from A to B is given by 260 / u hours. 5. The difference in time it will take for the car compared to the bus to travel the entire distance is given by 260 / x - 260 / u hours. 6. The ratio of the time it will take for the car to the time it will take for the bus to travel the entire distance is given by (260 / u) / (260 / x). 7. The closing speed of the bus and the car is given by x + u km/h. 8. The time it will take for the bus and the car to meet after the start of their journey is given by 260 / (x + u) hours.

Answers:

1. The difference in speed between the bus and the car is u - x km/h. 2. The ratio of the bus's speed to the car's speed is x / u. 3. The time it will take for the bus to travel the entire distance from A to B is 260 / x hours. 4. The time it will take for the car to travel the entire distance from A to B is 260 / u hours. 5. The difference in time it will take for the car compared to the bus to travel the entire distance is 260 / x - 260 / u hours. 6. The ratio of the time it will take for the car to the time it will take for the bus to travel the entire distance is (260 / u) / (260 / x). 7. The closing speed of the bus and the car is x + u km/h. 8. The time it will take for the bus and the car to meet after the start of their journey is 260 / (x + u) hours.

Please note that the specific values of x and u were not provided, so the calculations are based on the given expressions.
