The boat went from one pier to another 240 km and came back. Find the average speed of the boat along the entire route if its own speed is 18 km / h and the current speed is 2 km / h.

Distance – 240 km.
The speed of the boat is 18 km / h.
The current speed is 2 km / h.
What is the average speed of the boat?
1) 18 + 2 = 20 (km / h) downstream speed.
2) 18-2 = 16 (km / h) upstream speed.
3) (16 + 20) / 2 = 18 (km / h) average speed.
The average speed of the boat is 18 km / h.
