2) 32+2=34 (км/ч) скорость катера по течению

Answer 2

Calculating Boat Speed Relative to the Current

To find the speed of the boat relative to the current, we can use the formula: Boat speed in still water = (Speed of boat against the current + Speed of boat with the current) / 2

Given: - Speed of the boat = 32 km/h - Speed of the boat against the current = 30 km/h

Using the formula: Boat speed in still water = (30 + x) / 2 where x is the speed of the boat with the current.

Calculation

Substituting the given values: 32 = (30 + x) / 2

Solving for x: 32 * 2 = 30 + x 64 = 30 + x x = 64 - 30 x = 34

So, the speed of the boat with the current is 34 km/h.
