Question

Пароход плыл 1,5 часа по реке со скоростью 36,4км\ч.С какой скоростью он проплыл?

Answer 1

Средняя скорость - весь путь делим на всё время.
1) S1 = 36,4 * 1,5 = 54,6 км  по реке.
2) S2 = 33.6 * 0.5 = 16.8 км по озеру.
3) S = 54.6 + 16.8 = 71.4 км - весь путь
4) Т = 1,5 + 0,5 = 2 ч -  всё время
5) Vср = 71,4 : 2 = 35,7 км/ч - средняя скорость - ОТВЕТ

Answer 2

Calculation of Speed

To calculate the speed at which the steamboat traveled, we can use the formula:

Speed = Distance / Time

In this case, the distance traveled is not given, but we know that the steamboat traveled for 1.5 hours at a speed of 36.4 km/h.

Using the formula, we can calculate the distance traveled:

Distance = Speed x Time

Distance = 36.4 km/h x 1.5 hours

Distance = 54.6 km

Therefore, the steamboat traveled a distance of 54.6 kilometers.

Speed of the Steamboat

Now that we know the distance traveled, we can calculate the speed at which the steamboat traveled.

Speed = Distance / Time

Speed = 54.6 km / 1.5 hours

Speed = 36.4 km/h

Therefore, the steamboat traveled at a speed of 36.4 km/h.
