Question

Скорость катера по озеру в стоячей воде равна 19,3 километров в час скорость течения реки равна 2,4 километров час с какой скоростью плывет катер по течению реки и против течения реки??

Answer 1

1) 19,3+2,4=21,7 км/ч скорость катера пл течению реки
2) 19,3-2,4=16,9 км/ч скорость катера против течения реки
Ответ : 21,7 км/ч скорость катера по течению реки. 16,9 км/ч скорость катера против течения реки

Answer 2

Calculating Boat Speed in Still Water, Downstream, and Upstream

To calculate the speed of the boat in still water, downstream, and upstream, we can use the following formulas:

- Speed of the boat in still water (B) = (Speed in downstream + Speed in upstream) / 2 - Speed downstream (D) = Speed in still water + Speed of the current - Speed upstream (U) = Speed in still water - Speed of the current

Given: - Speed in still water (B) = 19.3 km/h - Speed of the current = 2.4 km/h

Using the above formulas, we can calculate the boat's speed in still water, downstream, and upstream.

Calculations

- Speed of the boat in still water (B) = (19.3 + 0) / 2 = 9.65 km/h - Speed downstream (D) = 19.3 + 2.4 = 21.7 km/h - Speed upstream (U) = 19.3 - 2.4 = 16.9 km/h

So, the boat's speed in still water is 9.65 km/h, downstream is 21.7 km/h, and upstream is 16.9 km/h.

These calculations are based on the given speeds and the formulas for calculating boat speed in still water, downstream, and upstream.
