The speed of the boat in still water is 10 km / h, the speed of the river is 2 km / h. The distance between the berths is 48 km. How long can the boat cover this distance along the river?

Let’s find the value of the speed of this boat along the river, for this we need the value of the own speed of this boat, add the value of the speed of the river:
10 + 2 = 12 km / h – this is the value of the speed of this boat along the river;
Let’s find the time for which this boat will be able to travel the specified distance, for this we need to divide the distance by the value of the speed of this boat along the river:
48:12 = 4 hours – this is the time the boat will be able to cover this distance.
Answer: 4 hours – this is the time the boat will be able to cover this distance.
