Question

Моторная лодка движется по течению реки со скоростью 24км/ч.Найдите скорость лодки против течения реки, если скорость течения реки 2,4 км/ч

Answer 1

1) 24 - 2,4 = 21,6 (км/ч) - собственная скорость моторной лодки
2) 21,6 - 2,4 = 19,2 (км/ч) - скорость моторной лодки против течения реки

Ответ: скорость моторной лодки против течения реки равна 19,2 км/ч

Answer 2

Calculating the Boat's Speed Against the Current

To find the speed of the boat against the current, we can use the formula: speed of boat against the current = speed of boat in still water - speed of the current.

Given: - Speed of the boat in the direction of the current = 24 km/h - Speed of the current = 2.4 km/h

Using the formula, we can calculate the speed of the boat against the current as follows:

speed of boat against the current = 24 km/h - 2.4 km/h = 21.6 km/h.

This means that the speed of the boat against the current is 21.6 km/h.

Therefore, the speed of the boat against the current is 21.6 km/h.
