| **The distance between cities A and B by water is 48 km. In how many hours will a galley and a frigate meet, which went out at the same time towards each other, if the speed of one is 10 km / h, and the speed of the other is 20 km / h?**

Determine with what speed the galley and the frigate are moving towards each other.

To do this, add the speed of the frigate to the speed of the galley.

We get:

20 + 10 = 30 km / h.

We find the time of their meeting.

To find it, the distance between cities A and B should be divided by the obtained speed of convergence of the galleys and the frigate.

The result will be:

48/30 = 1.6 hours.

If we convert the time into hours and minutes, we get:

1 h + 0.6 * 60 = 1 h 36 min.

Answer: They will meet in 1.6 hours.
