The motor ship sailed 4.5 hours against the current and 0.8 hours along the river.

The motor ship sailed 4.5 hours against the current and 0.8 hours along the river. What way did the motor ship go if its speed against the current is 24.6 km / h, and the speed of the current is 1.8 km / h?

1. Let us determine how many kilometers the motor ship passed against the river flow, if it is known that it was on the way for 4.5 hours and moved at a speed of 24.6 kilometers per hour.
4.5 * 24.6 = 110.7 kilometers.
2. Let’s find at what speed the motor ship went downstream of the river per hour.
24.6 + 1.8 + 1.8 = 28.2 kilometers.
3. Let’s calculate the distance traveled along the river in 0.8 hours.
28.2 * 0.8 = 22.56 kilometers.
4. Let’s find out which way the ship went.
110.7 + 22.56 = 133.26 kilometers.
Answer: The motor ship covered only 133.26 kilometers.
