Question

Решите задачу машина в первый день за 9ч прошла 522км.Во второй день она была в пути 7 ч увеличив скорость на 6 км\ч .Определили расстояние,которое прошла машина за эти два дня

Answer 1

522:9=58 км/ ч
58+6=64 км/ч
7×64=448
522+448=970

Answer 2

1)522:9= 58 км/ч- скорость в 1 день 2) 58+6=64 км/ч - скорость в 2 день 3.) 7*64= 448 км- прошла во 2 день 4. 522+488=970 км Ответ: всего 970 км

Answer 3

Problem Analysis

We are given that a car traveled 522 km in the first day, and on the second day, it increased its speed by 6 km/h and traveled for 7 hours. We need to determine the total distance traveled by the car over these two days.

Solution

To solve this problem, we can calculate the distance traveled on each day separately and then add them together.

Let's start by calculating the distance traveled on the first day. We are given that the car traveled 522 km in 9 hours. Therefore, the speed of the car on the first day can be calculated as:

Speed on the first day = Distance / Time = 522 km / 9 hours

Now, let's calculate the distance traveled on the second day. We are given that the car traveled for 7 hours at a speed that is 6 km/h higher than the speed on the first day. Therefore, the speed on the second day can be calculated as:

Speed on the second day = Speed on the first day + 6 km/h

Finally, we can calculate the distance traveled on the second day using the speed on the second day and the time of 7 hours:

Distance on the second day = Speed on the second day * Time = (Speed on the first day + 6 km/h) * 7 hours

To find the total distance traveled over the two days, we can add the distances traveled on each day:

Total distance = Distance on the first day + Distance on the second day

Let's calculate the values:

Speed on the first day = 522 km / 9 hours = 58 km/h

Speed on the second day = 58 km/h + 6 km/h = 64 km/h

Distance on the second day = 64 km/h * 7 hours = 448 km

Total distance = 522 km + 448 km = 970 km

Therefore, the car traveled a total distance of 970 km over the two days.

Answer

The car traveled a total distance of 970 km over the two days.
