The speed of the boat against the current is 12.3 km / h, the own speed of the boat is 14.1 km / h. How far will the boat go downstream in 2 hours?
1. Let’s find the speed of the current:
14.1 – 12.3 = 1.8 (km / h).
2. Find the speed of the boat downstream:
14.1 + 1.8 = 15.9 (km / h).
3. Find the distance that the boat will cover in 3 hours downstream:
S = V * t = 15.9 * 2 = 31.8 (km).
Answer: the boat will go downstream in 2 hours 31.8 km.
