Question

Из одного пункта в противоположных направлениях выехали две автомашины со скоростью 60км/ч и 80км/ч. Через сколько часов расстояние между ними будет 560 км?

Answer 1

Х - неизвестное время
х*(60+80)=560
140х=560
х=4 часа

Answer 2

60+80=140 V удаления 560:140=4часа

Answer 3

Problem Analysis

We have two cars traveling in opposite directions with speeds of 60 km/h and 80 km/h. We need to find out how many hours it will take for the distance between them to be 560 km.

Solution

To find the time it takes for the distance between the two cars to be 560 km, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two cars since they are traveling in opposite directions.

Let's calculate the time it takes:

Relative Speed = 60 km/h + 80 km/h = 140 km/h

Time = 560 km / 140 km/h = 4 hours

Therefore, it will take 4 hours for the distance between the two cars to be 560 km.

Answer

The distance between the two cars will be 560 km after 4 hours.
