Question

Скорость лодки против течения 12 километров в час скорость течения реки два километра в час Какое расстояние пройдет лодка по течению реки за 2,5 часа

Answer 1

1)12+2,5=14,5 км ч скорость лодки по течению                                                2)12-2,5=9,5 км ч скорость лодки против течения
3) 9,5*2,5=23,75  км проплывет лодка против течения
4)14,5*2,5=36,25 км проплывет лодка по течению

Answer 2

Calculation of Distance Traveled by the Boat

To calculate the distance traveled by the boat against the current of the river, we need to consider the speed of the boat and the speed of the current.

Given: - Speed of the boat against the current: 12 kilometers per hour - Speed of the river current: 2 kilometers per hour - Time: 2.5 hours

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

Distance = (Speed of the boat - Speed of the current) * Time

Substituting the given values into the formula:

Distance = (12 - 2) * 2.5

Calculating the result:

Distance = 10 * 2.5 = 25 kilometers

Therefore, the boat will travel a distance of 25 kilometers against the current of the river in 2.5 hours.
