Question

Скорость моторной лодки в стоячей воде равна 16 км/ч,скорость течения реки-2 км/ч.Какое расстояние пройдет за 3 часа моторная лодка против течения реки?

Answer 1

1)16-2=14(км/ч)-скорость моторной лодки против течения 
2)14*3=42(км)-расстояние каторое проплывёт моторная лодка за 3 часа
Ответ:42 км

Answer 2

Calculation of Distance Traveled

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

Given: - Speed of the motorboat in still water: 16 km/h - Speed of the river current: 2 km/h - Time traveled: 3 hours

To find the distance traveled by the motorboat against the river current, we can use the following formula:

Distance = (Speed of the motorboat - Speed of the river current) * Time

Substituting the given values into the formula:

Distance = (16 km/h - 2 km/h) * 3 hours

Simplifying the equation:

Distance = 14 km/h * 3 hours

Distance = 42 km

Therefore, the motorboat will travel a distance of 42 kilometers against the river current in 3 hours.
