Question

Автомобиль и автобус начали одновременно движение в противоположных направлениях. Автобус за 4 часа преодолел 180 км , а автомобиль преодолел это же расстояние ща 3 часа . На каком растоянии друг от друга будут автомобиль и автоюус через 5 часов , если сначала между ними было 26 км?

Answer 1

Ответ:

551 км

Пошаговое объяснение:

Нужно найти скорость автобуса и автомобиля (разделить расстояние на время):

Скорость автобуса: 180/4=45 км/ч

Скорость автомобиля: 180/3=60 км/ч

За 5 часов автомобиль преодолеет расстояние: 60*5=300 км

За 5 часов автобус преодолеет расстояние: 45*5=225 км

Вычислим расстояние: 300+225+26=551 км

Answer 2

Problem Analysis

We are given that a car and a bus start moving simultaneously in opposite directions. The bus covers a distance of 180 km in 4 hours, while the car covers the same distance in 3 hours. We need to find the distance between the car and the bus after 5 hours, given that initially, they were 26 km apart.

Solution

To solve this problem, we can use the concept of relative speed. The relative speed between the car and the bus is the sum of their individual speeds. Let's assume the speed of the car is C km/h and the speed of the bus is B km/h.

We are given that the bus covers a distance of 180 km in 4 hours, so we can calculate the speed of the bus using the formula:

B = Distance / Time = 180 km / 4 hours = 45 km/h Similarly, we are given that the car covers the same distance of 180 km in 3 hours, so we can calculate the speed of the car using the formula:

C = Distance / Time = 180 km / 3 hours = 60 km/h Now, we can find the relative speed between the car and the bus:

Relative Speed = C + B = 60 km/h + 45 km/h = 105 km/h

To find the distance between the car and the bus after 5 hours, we can use the formula:

Distance = Relative Speed * Time = 105 km/h * 5 hours = 525 km

However, we need to consider that initially, the car and the bus were 26 km apart. So, we subtract this initial distance from the total distance:

Final Distance = Distance - Initial Distance = 525 km - 26 km = 499 km

Therefore, after 5 hours, the car and the bus will be 499 km apart.

Answer

After 5 hours, the car and the bus will be 499 km apart if initially, they were 26 km apart.
