Question

Скорость катера , движущегося по течению 47,7 км / ч . Найдите скорость катера придвижении в стоячей воде против течения , если скорость течения реки 3 , 7 км/ч

Answer 1

47,7-3,7=44 км/ч собственная скорость катера
44-3,7= 40,3 км/ч скорость против течения реки

Answer 2

Calculation of Boat Speed in Still Water

To find the speed of the boat in still water when moving against the current, we can use the following formula:

Boat Speed in Still Water = Boat Speed in Current + Current Speed

Given: - Boat Speed in Current = 47.7 km/h - Current Speed = 3.7 km/h

Using the formula, we can calculate the boat speed in still water as follows:

Boat Speed in Still Water = 47.7 km/h + 3.7 km/h = 51.4 km/h.

Therefore, the speed of the boat in still water when moving against the current is 51.4 km/h.
