Answer 1

скорость течения лодки в стоячей воде 3, 5 км/ч, а скорость течения реки 1, 3 км/ ч. сколько километров пройдёт лодка за 2 часа по течению реки?

скорость по течению:
3,5+1,3=4,8 км/ч
за 2 часа пройдет:
4,8*2=9,6 км

ответ:9,6 км

Answer 2

Calculation of the Boat's Distance Traveled

To calculate the distance traveled by the boat in 2 hours against the river current, we need to consider the boat's speed in still water and the speed of the river current.

Given: - Speed of the boat in still water: 3.5 km/h - Speed of the river current: 1.3 km/h - Time: 2 hours

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

Distance = (Speed of the boat in still water - Speed of the river current) * Time

Substituting the given values into the formula:

Distance = (3.5 km/h - 1.3 km/h) * 2 hours

Calculating the values:

Distance = 2.2 km/h * 2 hours

Distance = 4.4 km

Therefore, the boat will travel a distance of 4.4 kilometers against the river current in 2 hours.
