Question

Собственная скорость теплохода равна 27 км/ч, скорость течения реки 3 км/ч. Сколько времени затратит теплоход на путь между двумя пристанями, расстояние между которыми 120 км?

Answer 1

По течению --------------------------------------------------------- 4 часа --------------------------------------------------------- 27+3=30 км/ч --------------------------------------------------------- 120/30=4 часа --------------------------------------------------------- --------------------------------------------------------- Против течения --------------------------------------------------------- 5 часов --------------------------------------------------------- 27-3=24км/ч --------------------------------------------------------- 120/24=5 часов

Answer 2

Calculation of Time Taken by the Ship

To calculate the time taken by the ship to travel between the two ports, we need to consider the speed of the ship and the speed of the river current.

Given: - Speed of the ship = 27 km/h - Speed of the river current = 3 km/h - Distance between the two ports = 120 km

To calculate the time taken, we can use the formula:

Time = Distance / (Speed of the ship + Speed of the river current)

Substituting the given values:

Time = 120 km / (27 km/h + 3 km/h)

Simplifying the equation:

Time = 120 km / 30 km/h

Calculating the time:

Time = 4 hours

Therefore, the ship will take 4 hours to travel between the two ports.
