Question

Пароход по течению реки проходит 23 целых три восьмых км в час . скорость течения реки 2 целых одна вторая км в час.сколько километров пройдёт пароход за 1 час против течения?

Answer 1

Ответ : Пароход пройдет за 1 час против течения реки : 23 3/8 - (2 1/2) * 2 = 23 3/8 - 5 = 18 3/8 км/ч 

Answer 2

Calculation of the Distance Traveled by the Steamboat

To calculate the distance traveled by the steamboat against the current, we need to subtract the speed of the current from the speed of the steamboat.

Given: - Speed of the steamboat = 23 3/8 km/h - Speed of the current = 2 1/2 km/h

To find the distance traveled by the steamboat against the current in 1 hour, we subtract the speed of the current from the speed of the steamboat:

Distance traveled by the steamboat against the current = Speed of the steamboat - Speed of the current

Let's perform the calculation:

Speed of the steamboat = 23 3/8 km/h = 23.375 km/h Speed of the current = 2 1/2 km/h = 2.5 km/h

Distance traveled by the steamboat against the current = 23.375 km/h - 2.5 km/h = 20.875 km/h

Therefore, the steamboat will travel approximately 20.875 kilometers against the current in 1 hour.

Please note that the above calculation assumes a constant speed and does not take into account other factors such as changes in the current or the efficiency of the steamboat's propulsion system.
