Question

Автобус выехал из пункта А в пункт Б через 1, 5 часа вслед за ним из пункта А выехал автомобиль который приехал в пункт Б одновременно с автобусом Чему равно расстояние между пунктами А и Б если известно что автобус ехал со скоростью 60 километров час а автомобиль со скоростью 80 км в час

Answer 1

Пусть весь путь равен  x, а время автобуса - y, тогда время автомобиля y-1,5. Пользуясь формулой S=Vt, составим и решим уравнение

60y=80(y-1,5)

60y=80y-120

-20y=-120

y=6ч

x=60*6=360км

Ответ: 360км

Answer 2

Calculation of Distance between Points A and B

To calculate the distance between points A and B, we need to determine the time it took for both the bus and the car to reach point B from point A.

Given that the bus departed from point A and arrived at point B after 1.5 hours, and the car departed from point A and arrived at point B simultaneously with the bus, we can conclude that the car also took 1.5 hours to travel from point A to point B.

Now, let's calculate the distance between points A and B using the formula:

Distance = Speed × Time

The speed of the bus is given as 60 km/h, and the speed of the car is given as 80 km/h. Since both vehicles took the same amount of time to travel from point A to point B, we can use either speed value in the formula.

Let's calculate the distance using the speed of the bus:

Distance = 60 km/h × 1.5 hours = 90 kilometers

Therefore, the distance between points A and B is 90 kilometers.
