The motor ship went along the river for 2.5 hours, and against the current for 3.2 hours. What is the general path of the motor ship, if its own speed is 22 km / h, and the speed of the current is 3 km / h

1) Let’s find out what speed the motor ship developed along the river, if the speed of the motor ship was 22 km / h, and the speed of the river was 3 km / h.

22 + 3 = 25 km / h.

2) Let’s find out what distance the motor ship traveled along the river, if it was on the way for 2.5 hours and went at a speed of 25 km / h.

25 * 2.5 = 62.5 km.

3) Let’s find out what speed the motor ship has going against the stream of the river.

22 – 3 = 19 km / h.

4) Find out the distance traveled upstream.

3.2 * 19 = 60.8 km.

5) Find out the total distance.

60.8 + 62.5 = 123.3 km.

Answer: the motor ship covered 123.3 km.
