Question

Два автомобиля расстояние между ними которыми 60 км движутся в одном направлении скорость первого автомобиля равна 70 км/ч а скорость второго автомобиля движущегося вслед за первым равна. 80 км/ч какое расстояние будет между ними через 5 часов

Answer 1

70×5=350км
80×5=400км

350+60=410км
410-400=10км

ответ: расстояние между ними через 3 часа 10 км

Answer 2

Calculation of the Distance between the Two Cars

To calculate the distance between the two cars after 5 hours, we need to consider their speeds and the time elapsed.

Given: - Distance between the two cars: 60 km - Speed of the first car: 70 km/h - Speed of the second car: 80 km/h

We can use the formula: distance = speed × time.

Let's calculate the distance traveled by each car after 5 hours:

- Distance traveled by the first car: 70 km/h × 5 hours = 350 km - Distance traveled by the second car: 80 km/h × 5 hours = 400 km

Now, let's calculate the distance between the two cars after 5 hours:

- Distance between the two cars = Distance traveled by the second car - Distance traveled by the first car - Distance between the two cars = 400 km - 350 km = 50 km

Therefore, the distance between the two cars after 5 hours will be 50 km.
