Question

Катер,двигаясь против течения,за 6 часов прошел 177,6 кг.Найдите скорость катера(в стоячей воде),если скорость течения равна 2,8км/ч

Answer 1

Скорость катера против течения 177,6:6 = 29,6 км/ч.
Скорость катера в стоячей воде 29,6+2,8 = 32,4 км/ч.

Answer 2

Calculation of Boat Speed

To find the speed of the boat in still water, we can use the formula:

Boat Speed = Distance / Time

In this case, the boat traveled a distance of 177.6 km in 6 hours while moving against a current with a speed of 2.8 km/h. To calculate the boat's speed in still water, we need to subtract the speed of the current from the boat's actual speed.

Let's calculate the boat's speed in still water:

Boat Speed = (Distance + (Speed of Current * Time)) / Time

Substituting the given values:

Boat Speed = (177.6 + (2.8 * 6)) / 6

Calculating the expression:

Boat Speed = (177.6 + 16.8) / 6

Boat Speed = 194.4 / 6

Boat Speed = 32.4 km/h

Therefore, the speed of the boat in still water is 32.4 km/h.
