The boat’s own speed is 7 times the speed of the river. Moving downstream, the boat sailed 179.2 km in 5.6 hours. Find your own speed of the boat and the speed of the river.
1. Let’s find how many kilometers per hour the boat sailed along the river, if it is known that in 5.6 hours it sailed 179.2 kilometers.
179.2 / 5.6 = 32 kilometers.
2. Let’s calculate the speed of the river.
32/8 = 4 kilometers.
3. Find out the boat’s own speed, if it is known that it is 7 times the speed of the river.
7 * 4 = 28 kilometers.
Answer: The speed of the river is four kilometers per hour, and the boat’s own speed is twenty-eight kilometers per hour.
