Question

Пароход, двигаясь против течения со скоростью 16 км/ч, проходит расстояние между двумя пристанями за 4 ч. За какое время он пройдёт то же расстояние по течению, если его скорость в этом случае равна 6 м/с?

Answer 1

В данной задаче составляем пропорцию:
V2*t2=V1*t1
Откуда t2=V1*t1/V2=3 часа.

Answer 2

Calculation of Time to Travel the Same Distance with the Current

To calculate the time it takes for the steamship to travel the same distance with the current, we can use the formula:

Time = Distance / Speed

Given that the speed of the steamship against the current is 16 km/h and it takes 4 hours to travel the distance between the two piers, we can calculate the distance using the formula:

Distance = Speed * Time

Substituting the given values:

Distance = 16 km/h * 4 hours = 64 km

Now, to calculate the time it takes for the steamship to travel the same distance with the current, we need to find the speed of the steamship with the current. The speed of the steamship with the current is given as 6 m/s.

Converting the speed from m/s to km/h:

Speed = 6 m/s * 3.6 km/h = 21.6 km/h

Using the formula mentioned earlier:

Time = Distance / Speed = 64 km / 21.6 km/h = 2.96 hours

Therefore, it will take approximately 2.96 hours for the steamship to travel the same distance with the current, given its speed of 6 m/s.
