Question

Теплоход, скорость которого в неподвижной воде равна 18 км/ч, проходит по течению реки и после стоянки возвращается в исходный пункт. Скорость течения равна 4 км/ч, стоянка длится 6 часов, а в исходный пункт теплоход возвращается через 33 часа после отплытия из него. Найти расстояние между пунктами.

Answer 2

Calculating the Distance Between Points

To calculate the distance between the points, we can use the formula: distance = speed × time. We'll break down the given information and use it to find the distance.

1. Speed of the Boat in Still Water: - The speed of the boat in still water is given as 18 km/h.

2. Speed of the River's Current: - The speed of the river's current is given as 4 km/h.

3. Duration of the Stoppage: - The stoppage duration is given as 6 hours.

4. Return to the Starting Point: - The boat returns to the starting point after 33 hours.

Using this information, we can calculate the distance between the points.

Calculations

- Let's denote the distance between the points as D.

- The boat's speed in the direction of the current is 18 + 4 = 22 km/h, and against the current is 18 - 4 = 14 km/h.

- The time taken to travel downstream is 33 hours, and the time taken to travel upstream is 33 - 6 = 27 hours.

- Using the formula distance = speed × time, we can calculate the distance between the points.

- Downstream distance: D = 22 km/h × 33 h = 726 km - Upstream distance: D = 14 km/h × 27 h = 378 km

Conclusion

The distance between the points is 726 km downstream and 378 km upstream.
