Question

как узнать скорость катера за течением,если его скорость против течения 18,3кмза час,а собственная скорость 19,8км в час

Answer 1

Відповідь:

Покрокове пояснення:

Скорость течения равна:

19,8 - 18,3 = 1,5 км./час.

Скорость катера по течению равна:

19,8 + 1,5 = 21,3 км./час.

Answer 2

Calculating Boat Speed Against the Current

To calculate the speed of a boat against the current, you can use the formula:

Boat speed against the current = Boat's speed in still water - Speed of the current

In this case, the boat's speed in still water is 19.8 km/h, and the speed against the current is 18.3 km/h. Using the formula, we can calculate the speed of the current.

Boat speed against the current = 19.8 km/h - 18.3 km/h

This gives us the boat's speed against the current.

Let's calculate it: 19.8 km/h - 18.3 km/h = 1.5 km/h

So, the speed of the current is 1.5 km/h.
