Question

Реши задачу с помощью уравнения. Путешественники ехали первый день со скоростью 60 км/ч 6 часов и несколько часов проехали во второй день со скоростью 65 км/ч. Весь их путь составил 870 км. Сколько времени потратили путешественники во второй день ​

Answer 1

Ответ:

7,5 часа они ехали на второй день

Пошаговое объяснение:

60*6=360км

870-360=510км

510:65=7,5

Но я не на что процентов уверен что это правильно

Answer 2

Problem Analysis

To solve this problem, we can use the equation: distance = speed × time. We know the distance traveled on the first day, the speed on the first day, and the total distance traveled. We need to find the time spent on the second day.

Solution

Let's denote the time spent on the second day as t.

On the first day: - Speed = 60 km/h - Time = 6 hours

On the second day: - Speed = 65 km/h - Time = t hours

The total distance traveled is 870 km.

Using the equation distance = speed × time, we can set up the following equation:

(60 km/h × 6 hours) + (65 km/h × t hours) = 870 km

Simplifying the equation:

360 km + 65t km = 870 km

65t km = 870 km - 360 km

65t km = 510 km

Now, we can solve for t:

t = 510 km / 65 km/h

t ≈ 7.85 hours

Therefore, the travelers spent approximately 7.85 hours on the second day.

Answer

The travelers spent approximately 7.85 hours on the second day.
