The motor ship moved at a speed of 0.3 hours along the river and 0.6 hours against the river.

The motor ship moved at a speed of 0.3 hours along the river and 0.6 hours against the river. What way did the ship take this time, if the own speed of the ship is 24.3 km / h, and the speed of the river is 3.5 km / h.

1. Find how many kilometers in 1 hour the motor ship passed along the river.

24.3 + 3.5 = 27.8 kilometers.

2. Let’s calculate at what speed per hour he was traveling against the river.

24.3 – 3.5 = 20.8 kilometers.

3. Let’s determine how many kilometers the ship sailed in 0.3 hours along the river.

27.8 * 0.3 = 8.34 kilometers.

4. Find out the distance that he traveled against the river in 0.6 hours.

20.8 * 0.6 = 12.48 kilometers.

5. Let’s find the entire route covered by the motor ship.

8.34 + 12.48 = 20.82 kilometers.

Answer: The motor ship covered 20.82 kilometers.
