The boat sailed along the river for 2.4 hours at a distance of 67.2 km. The speed of the river is 2.5 km / h. Find the boat’s own speed.

From the condition it is known that the boat sailed along the river for 2.4 hours. The total distance covered is 67.2 kilometers, the speed of the river is 2.5 km / h.

First, let’s calculate the speed with which the boat was going along the river.

1) 2.4 * 2.5 = 6 (km / h) – speed of the boat along the river.

Next, we calculate the total distance that the boat has traveled along the river.

2) 67.2 – 6 = 61.2 (kilometers) – the boat drove along the river in total.

Now we can answer the main question of the problem and calculate the boat’s own speed.

3) 61.2: 2.4 = 25.5 (km / h) – own speed of the boat.

Answer: the boat’s own speed is 25.5 km / h.
