Question

С автостоянки одновременно в противоположных направлениях выехали две автомашины. скорость движения одной машины 50 км/ч а другой 70км/ч . Через сколько часов расстояние между ними будет 360 км?

Answer 1

1) 50+70=120 (км/ч) - общая скорость отдаления
2) 360:120=3(ч) - через 3 часа между автомобилями будет 360 км

Answer 2

50+70=120(км/ч)-скорость отдаления
360/120=3(ч)-время

Answer 3

Calculation of the Time it Takes for the Distance Between Two Cars to be 360 km

To calculate the time it takes for the distance between two cars to be 360 km, we need to determine their relative speed. In this case, one car is traveling at a speed of 50 km/h, while the other is traveling at a speed of 70 km/h.

To find the relative speed, we subtract the speed of the slower car from the speed of the faster car:

Relative speed = Speed of the faster car - Speed of the slower car

Relative speed = 70 km/h - 50 km/h = 20 km/h

Now, we can calculate the time it takes for the distance between the two cars to be 360 km using the formula:

Time = Distance / Relative speed

Time = 360 km / 20 km/h = 18 hours

Therefore, it will take 18 hours for the distance between the two cars to be 360 km.

Note: The calculation assumes that the cars are moving in opposite directions from the same starting point.
