Question

Пароход плывет по течению реки со скоростью 45 км/ч. Какое расстояние пароход проплывет за 2,5 часа против течения реки, если скорость течения реки 2,5 км/ч? 100 км152 KM120 KM138 км​

Answer 1

Ответ:

100км

Пошаговое объяснение:

1)2,5+2,5=5

2)45-5=40

3)40*2,5=200

Answer 2

Calculation of Distance Traveled

To calculate the distance the steamboat will travel against the current of the river, we need to subtract the speed of the river current from the speed of the steamboat and then multiply the result by the time traveled.

Given: - Speed of the steamboat: 45 km/h - Speed of the river current: 2.5 km/h - Time traveled: 2.5 hours

To find the distance traveled, we can use the formula:

Distance = (Speed of the steamboat - Speed of the river current) × Time traveled

Substituting the given values into the formula:

Distance = (45 km/h - 2.5 km/h) × 2.5 hours

Calculating the result:

Distance = (42.5 km/h) × 2.5 hours

Distance = 106.25 km

Therefore, the steamboat will travel 106.25 km against the current of the river in 2.5 hours.
