Question

Катер прошёл по течению реки 119км за5ч.какое расстояние пройдёт он против течения за 5ч,если скорость катера в стоячей воде равна 32,8км/ч

Answer 1

119:3,5 = 34 км/ч скорость катера по течению 34-32, 8 = 1,2 км/ч скорость реки (32,8 - 1,2)*5 =158 км пройдет катер против течения

Answer 2

Calculation of Distance Traveled Against the Current

To calculate the distance the boat will travel against the current in 5 hours, we need to determine the speed of the boat relative to the current.

Given: - Distance traveled with the current: 119 km - Time taken: 5 hours - Speed of the boat in still water: 32.8 km/h

To find the speed of the current, we can use the formula:

Speed of the current = (Distance traveled with the current) / (Time taken with the current)

Substituting the given values:

Speed of the current = 119 km / 5 hours

Using the formula for speed:

Speed = Distance / Time

We can rearrange the formula to solve for distance:

Distance = Speed * Time

Substituting the values:

Distance = (Speed of the boat in still water) * (Time taken against the current)

Now we can calculate the distance traveled against the current:

Distance = 32.8 km/h * 5 hours

Calculating the result:

Distance = 164 km

Therefore, the boat will travel a distance of 164 km against the current in 5 hours.
