When driving along the river, the distance of 48 km is covered by a pleasure boat in 3 hours. What is the proper speed of the boat if the river speed is 2 km / h?
1. Let us determine at what speed the pleasure boat was moving along the river, if it covered a distance of forty-eight kilometers in three hours:
48: 3 = 16 (km / h).
2. We find out what is the own speed of the pleasure boat, if it was moving along the river at a speed of sixteen kilometers per hour, and the speed of the river is two kilometers per hour:
16 – 2 = 14 (km / h).
Answer: The own speed of the pleasure boat is 14 kilometers per hour.
