Question

собственная скорость катера 26 км в час,скорость течения 3,5 км в час.катер плыл вверх по реке 4 часа.какой путь катера -вверх по реке или вниз по реке больше и на сколько?

Answer 1

1) 26 + 3,5 = 29,5 скорость катера вместе с течением вниз по реке
2) 29,5 * 4 = 118 км пройдет катер за 4 часа вниз по течению
3) 26 - 3,5 = 22,5 скорость катер вместе с течением вверх по реке
4) 22,5 * 4 = 90 км пройдет катер за 4 часа вверх по реке
5) 118 - 90 = 28 км
Путь катера вниз по реке больше на 28 км.

Answer 2

Calculation of the Distance Traveled by the Boat

To determine the distance traveled by the boat, we need to consider its speed and the time it spent traveling.

Given: - Boat speed: 26 km/h - Current speed: 3.5 km/h - Travel time: 4 hours

To calculate the distance traveled by the boat, we can use the formula:

Distance = Speed x Time

Let's calculate the distance traveled by the boat:

Distance = (Boat speed - Current speed) x Time

Distance = (26 km/h - 3.5 km/h) x 4 hours

Distance = 22.5 km/h x 4 hours

Distance = 90 km

Therefore, the boat traveled a distance of 90 kilometers.

Direction of Travel

To determine whether the boat traveled upstream or downstream, we need to compare the boat's speed with the current speed.

If the boat's speed is greater than the current speed, it means the boat is traveling downstream. If the boat's speed is less than the current speed, it means the boat is traveling upstream.

Given that the boat's speed is 26 km/h and the current speed is 3.5 km/h, we can conclude that the boat is traveling upstream.

Conclusion

The boat traveled a distance of 90 kilometers upstream along the river.
