Question

из одного того же посёлка одновременно вышли в противоположных направлениях автомашина и автобус. автобус шёл со скоростью 50 км/ час , а автомашина-80км/час . через сколько часов расстояние между автобусом и автомашиной будет 520 км?

Answer 1

1)50+80=130(км/ч)-скорость отдаления.

2)520:130=через 4часа расстояние между автобусом и автомашиной будет 520 км.

Answer 2

520\(50+80) = 4

Ответ: через 4 часа.

Answer 3

Calculation of the Time it Takes for the Distance Between the Bus and Car to be 520 km

To calculate the time it takes for the distance between the bus and car to be 520 km, we need to determine how long it takes for the two vehicles to cover a combined distance of 520 km.

The bus is traveling at a speed of 50 km/h, while the car is traveling at a speed of 80 km/h. Since they are moving in opposite directions, their speeds should be added together to calculate the combined speed.

The combined speed of the bus and car is 50 km/h + 80 km/h = 130 km/h.

To find the time it takes to cover a distance of 520 km at a speed of 130 km/h, we can use the formula:

Time = Distance / Speed

Substituting the values, we have:

Time = 520 km / 130 km/h

Calculating this, we find:

Time = 4 hours

Therefore, it will take 4 hours for the distance between the bus and car to be 520 km.
