| **The motor ship traveled for 4.5 hours against the river flow for 3.7 hours on a line. What way did the motor ship sailed if its speed against rolling is 23.7 km / h, and the speed of the current is 1.5 km / h.**

1. Let’s determine the own speed of the ship.

23.7 + 1.5 = 25.2 kilometers per hour.

2. Let’s calculate its speed downstream.

25.2 + 1.5 = 26.7 kilometers per hour.

3. Let’s find the length of the ship’s path a) downstream, b) upstream.

a) 26.7 * 3.7 = 98.79 kilometers.

b) 23.7 * 4.5 = 106.65 kilometers.

4. Find out how many kilometers along the stream and against the boat sailed.

98.79 + 106.65 = 205.44 kilometers.

Answer: 205.44 kilometers.
