The motor boat sailed 3.6 hours against the river and 1, 8 hours downstream. What path did the boat

The motor boat sailed 3.6 hours against the river and 1, 8 hours downstream. What path did the boat cover all the time, if the speed of the river flow is 1.2 km per hour, and the boat’s own speed is 22.4 km / h.

1) Determine the speed of the boat downstream.

22.4 + 1.2 = 23.6 kilometers per hour.

2) Find out what is the speed of the boat against the current.

22.4 – 1.2 = 21.2 kilometers per hour.

3) Let’s calculate what is the distance of the boat, which she sailed downstream.

23.6 * 1.8 = 42.48 kilometers.

4) What is the distance the boat swam against the current?

21.2 * 3.6 = 76.32 kilometers.

Let’s answer the question of the problem.

5) What path has the boat traveled during the entire movement?

42.48 + 76.32 = 118.8 kilometers.

Answer: The boat covered a distance of 118.8 kilometers.
