The current speed is 2.2 km / h. own speed of the boat 15.3 km / h. what way did the boat go if it sailed downstream for 3 hours, and against the current for 4 hours?
Determine the speed of the boat in each direction.
The downstream speed is equal to the sum of its own speed and the speed of the river flow.
15.3 + 2.2 = 17.5 km / h.
The upstream speed is equal to the difference.
15.3 – 2.2 = 13.1 km / h.
Find the distance traveled in each direction.
We multiply the speed of the boat by the travel time.
Will be:
17.5 * 3 = 52.5 km (downstream).
13.1 * 4 = 52.4 km (upstream).
The total distance was:
52.5 + 52.4 = 104.9 km.
Answer: The boat covered 104.9 km in total.
