Question

Плот проплыл 20 км за 5 ч . Каково скорость движения плота ?

Answer 1

Скорость 20:5=4(км/час)
Плот собственной скорости не имеет, это скорость течения реки.

Answer 2

Calculation of Speed

To calculate the speed of an object, we can use the formula:

Speed = Distance / Time

In this case, the distance traveled by the raft is 20 km and the time taken is 5 hours. Plugging these values into the formula, we can calculate the speed:

Speed = 20 km / 5 hours = 4 km/h

Therefore, the speed of the raft is 4 km/h.
