| **From the two piers, 2 heat ships set off towards each other. The distance between the piers is 180 km. They met after 6 hours. At what speed did the second motor ship go if the speed of the first was 15 km / h?**

Decision:

1) Let’s find the distance from the pier the first motor ship passed.

15 * 6 = 90 km

2) Let’s find what distance the second motor ship passed from the pier.

180 – 90 = 90 km

3) Find the speed of the second ship.

90/6 = 15 km / h

Answer: the speed of the second motor ship is 15 km / h.
