The boat sailed along the river for 4 hours, and against the current for 6 hours. the speed of the boat is 18 km / h, the speed of the river is 2 km / h. How many kilometers did the boat sail during this time?
4 hours – swam with the flow of the river.
6 hours – swam against the direction of the river.
18 km / h – boat pace.
18 + 2 = 20.
20 km / h – speed of the boat along with the river flow.
20 * 4 = 80.
80 km – the boat sailed along with the river.
18 – 2 = 16.
16 km / h – speed of the boat against the direction of the river flow.
16 * 6 = 96.
96 km – the boat sailed against the direction of the river.
96 + 80 = 176.
176 km – the entire route of the boat.
Solution: 176 km.
