Question

Моторная лодка движется по озеру со скорость 14км/ч.Какое рсстояние пройдет лодка за 2 ч, вигаясь по теч реки, если скоросьб реки 1,5 км/ч

Answer 1

Если скорость лодки в стоячей воде = 14 км/ч, то скорость лодки по течению реки будет составлять 14 + 1.5 = 15.5 км/ч

S = V * t
S = 15.5 * 2 = 31 км

Ответ: 31 км

Answer 2

(14+1,5)*2=31 км
Обьяснение.Так как он плывет по течению то Скорость лодки в стоячем состоянии + скорость реки =15,5 умножаем на время и находим какое расстояние он пройдет

Answer 3

Calculation of the Distance Traveled by the Boat

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

Given: - Speed of the boat: 14 km/h - Speed of the river: 1.5 km/h - Time: 2 hours

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

Distance = Speed × Time

In this case, the speed of the boat is the combined speed of the boat and the river. Since the boat is moving against the current of the river, we subtract the speed of the river from the speed of the boat.

Let's calculate the distance traveled by the boat:

Speed of the boat = 14 km/h Speed of the river = 1.5 km/h Time = 2 hours

Distance = (Speed of the boat - Speed of the river) × Time

Distance = (14 km/h - 1.5 km/h) × 2 hours

Distance = 12.5 km/h × 2 hours

Distance = 25 km

Therefore, the boat will travel a distance of 25 kilometers in 2 hours while moving against the current of the river.
