Question

При движении по течению реки расстояние 48 км прогулочный катер проходит за 3 ч. Какова собственная скорость катера, если скорость течения реки — 2 км/ч?

Answer 1

Скорость катера относительно берега равна
 48:3 = 16 км/ч.
Собственная скорость равна
16-2 = 14 км/ч

Answer 2

Calculation of the Boat's Speed

To calculate the boat's speed, we need to consider the distance traveled and the time taken. In this case, the boat traveled a distance of 48 km in 3 hours while moving with the current of the river, which has a speed of 2 km/h.

To find the boat's own speed, we can subtract the speed of the river's current from the total speed of the boat and the current. Let's denote the boat's speed as x km/h.

The boat's speed relative to the river's current is the sum of the boat's speed and the current's speed, which is x + 2 km/h.

Using the formula speed = distance / time, we can set up the equation:

x + 2 = 48 / 3

Simplifying the equation:

x + 2 = 16

Subtracting 2 from both sides:

x = 14

Therefore, the boat's own speed is 14 km/h.
