A boat and a motor boat sailed from two piers at the same time in opposite directions. After 3 hours, the distance between them became 270 km. At what speed the boat was sailing, if the speed of the boat was 34 km / h
1) Let’s determine how far the boat sailed from the pier, if we know that it sailed for 3 hours, and its speed was 34 km / h.
34 * 3 = 102 km.
2) Let’s find out how far the motor boat departed from the pier, if we know that the distance between the boat and the boat was 270 km, and the boat sailed at a distance of 102 km.
270 – 102 = 168 km.
3) Let’s determine the speed at which the motor boat moved, if in 3 hours it sailed 168 km.
168/3 = 56 km / h.
Answer: the speed of the motor boat was 56 km / h.
