Question

Педвелосиист за первые 3 мин проехал 1 км, а следующие 10 мин двигался со скоростью 36км/ч с какой скорость средней двигался велосипедист на всем участке

Answer 1

Почему "педвелосиист"? Ну ладно.
Чтобы узнать среднюю скорость надо поделить всё расстояние на всё время S/t .
S,км=1+10/60*36=7 км
t,мин=3+10=13 мин
S/t=7/13 км/мин = 420/13 км/ч = 7000/780 м/с ~= 9 м/с

Числа какие-то кривые, странно. Я всё проверял, ошибки не нашёл.

Answer 2

Calculation of Average Speed

To calculate the average speed of the cyclist on the entire route, we need to consider the distance covered and the time taken.

According to the information provided, the cyclist traveled 1 km in the first 3 minutes. After that, the cyclist traveled at a speed of 36 km/h for the next 10 minutes.

Let's break down the information:

- Distance covered in the first 3 minutes: 1 km - Time taken in the first 3 minutes: 3 minutes - Distance covered in the next 10 minutes: unknown - Time taken in the next 10 minutes: 10 minutes - Speed during the next 10 minutes: 36 km/h

To calculate the distance covered in the next 10 minutes, we can use the formula:

Distance = Speed × Time

Let's calculate the distance covered in the next 10 minutes:

Distance = 36 km/h × 10 minutes

To perform the calculation, we need to convert the time from minutes to hours:

10 minutes = 10/60 hours = 1/6 hours

Distance = 36 km/h × 1/6 hours

Simplifying the calculation:

Distance = 6 km

Now, we have the total distance covered by the cyclist:

- Distance covered in the first 3 minutes: 1 km - Distance covered in the next 10 minutes: 6 km

To calculate the average speed, we can use the formula:

Average Speed = Total Distance / Total Time

The total distance covered is 1 km + 6 km = 7 km.

The total time taken is 3 minutes + 10 minutes = 13 minutes.

To convert the total time to hours:

13 minutes = 13/60 hours = 13/60 hours

Average Speed = 7 km / 13/60 hours

Simplifying the calculation:

Average Speed = 7 km / (13/60) hours

Average Speed = 7 km × (60/13) km/h

Calculating the average speed:

Average Speed ≈ 32.31 km/h

Therefore, the average speed of the cyclist on the entire route is approximately 32.31 km/h.
