Question

Сделайте задачку.За першу годину поїзд пройшов 68км, а за другу - 84км. Знайди середню швидкість поїзда за цей час. Пишить будь- ласка з поясненням.

Answer 1

 ЗНАХОДИМО СЕРЕДНЮ ЩВИДКІСТЬ (68+84)/2=76КМ/ГОД 

Answer 2

(68+84)/2=152/2=76 средняя скорость поезда  сначала мы складываем, а потом делим на количество цифр и находим среднюю скорость

Answer 3

Calculating the Average Speed of the Train

To find the average speed of the train, we can use the formula:

Average Speed = Total Distance / Total Time

In this case, the total distance covered by the train is the sum of the distances covered in the first and second hours, which is 68 km + 84 km = 152 km.

The total time taken is 1 hour + 1 hour = 2 hours.

Now, we can calculate the average speed using the formula:

Average Speed = 152 km / 2 hours

Average Speed = 76 km/h

So, the average speed of the train for the given time period is 76 km/h.

Answer 4

Calculating the Average Speed of the Train

To find the average speed of the train, we can use the formula:

Average Speed = Total Distance / Total Time

In this case, the total distance covered by the train is the sum of the distances traveled in the first and second hours, and the total time is 2 hours.

So, the average speed of the train can be calculated as follows:

Total Distance = 68 km + 84 km = 152 km

Total Time = 2 hours

Average Speed = 152 km / 2 hours = 76 km/h

Therefore, the average speed of the train for the given time period is 76 km/h.
