Question

Из города в одном и том же направлении выехали легковой автомобиль и автобус. Скорость автомобиля 110 км/ч. Через 8 ч. расстояние между ними стало 560 км. Какова скорость автобуса (в км/ч)? Помогите прошу

Answer 1

Ответ:

40 км/ч скорость автобуса

Пошаговое объяснение:

1) 560 : 8 = 70 км/ч - скорость удаления

2) 110 - 70 = 40 км/ч

Answer 2

Problem Analysis

We are given that a car and a bus start from the same city and travel in the same direction. The car's speed is 110 km/h, and after 8 hours, the distance between them is 560 km. We need to find the speed of the bus.

Solution

Let's assume the speed of the bus is x km/h.

The distance traveled by the car in 8 hours is given by the formula:

Distance = Speed × Time

So, the distance traveled by the car is:

Distance_car = Speed_car × Time

Substituting the given values:

Distance_car = 110 km/h × 8 h = 880 km

The distance between the car and the bus after 8 hours is 560 km. Therefore, the distance traveled by the bus is:

Distance_bus = Distance_car - 560 km

Substituting the value of Distance_car:

Distance_bus = 880 km - 560 km = 320 km

Now, we can use the formula for the distance traveled by the bus:

Distance_bus = Speed_bus × Time

Substituting the values:

320 km = x km/h × 8 h

Simplifying the equation:

x km/h = 320 km / 8 h = 40 km/h

Therefore, the speed of the bus is 40 km/h.

Answer

The speed of the bus is 40 km/h.
