Question

Теплоход проходит 48 километров по течению реки за 3 часа а плот за 24 часа Какова скорость теплохода при движении по озеру

Answer 1

1) 48/24 = 2км/ч (Скорость течения реки)
2)48/3-2 =14км/ч (Скорость движения теплохода по озеру)
Ответ: Скорость движения теплохода по озеру составляет 14 км/ч

Answer 2

Calculation of the Speed of the Boat on the Lake

To calculate the speed of the boat on the lake, we can use the formula:

Speed = Distance / Time

Given that the boat travels 48 kilometers in 3 hours when moving against the current of the river, we can calculate the speed of the boat as follows:

Speed of the boat against the current = 48 km / 3 hours = 16 km/h.

Since the boat is moving on a lake, where there is no current, the speed of the boat on the lake will be the same as the speed of the boat against the current of the river. Therefore, the speed of the boat on the lake is 16 km/h.
