Question

Два автомобиля расстояние между которыми 60 км движутся в одном направлении скорость первого автомобиля равна 70 километров час а сколько 2 автомобиля движутся вслед за первым равна 80 километров час Какое расстояние будет между ними через 5 часов

Answer 1

1)80 - 70 = 10 (км/ч) - скорость сближения
2)10*5 = 50 (км) - они сблизились за 5 часов
3)60-50 = 10 (км) - расс. между ними через 5 часов
Ответ : 10 км

Answer 2

Calculation of Distance between the Two Cars

To calculate the distance between the two cars after 5 hours, we can use the formula:

Distance = Speed × Time

Let's calculate the distance between the two cars after 5 hours.

1. The speed of the first car is given as 70 kilometers per hour. 2. The speed of the second car, which is following the first car, is given as 80 kilometers per hour. 3. The initial distance between the two cars is 60 kilometers.

Using the formula, we can calculate the distance between the two cars after 5 hours:

Distance = (Speed of the first car × Time) + Initial Distance

Distance = (70 km/h × 5 h) + 60 km

Calculating the above expression:

Distance = 350 km + 60 km

Distance = 410 km

Therefore, the distance between the two cars after 5 hours will be 410 kilometers.
