Question

Швидкість автобуса на 25км/ч менше швидкості легкового автомобіля. Автобус за 3 год проходить такий же шлях, як легковий автомобіль за 2 год. Знайдіть швидкість автобуса.

Answer 1

Ответ:

50км / год

Пошаговое объяснение:

x*3=(x+25)*2

3x=2x+50

3x-2x=50

1x=50

Відповідь 50км/год

Answer 2

Calculation of the Bus Speed

To find the speed of the bus, we can use the information given in the question. Let's denote the speed of the car as C and the speed of the bus as B.

According to the question, the bus travels the same distance as the car in 3 hours, while the car takes 2 hours. We can set up the following equation based on the time and speed relationship:

Distance = Speed × Time

For the car: Distance = C × 2

For the bus: Distance = B × 3

Since the distances are the same, we can equate the two equations:

C × 2 = B × 3

Now, we are given that the speed of the bus is 25 km/h less than the speed of the car. We can express this relationship as:

B = C - 25

Substituting this into the equation above, we get:

C × 2 = (C - 25) × 3

Simplifying the equation:

2C = 3C - 75

C = 75

Therefore, the speed of the car is 75 km/h.

To find the speed of the bus, we substitute the value of C into the equation:

B = C - 25 = 75 - 25 = 50

Therefore, the speed of the bus is 50 km/h.
