The boat’s own speed is 28.3 km / h and the speed of the river is 2.6 km / h. moving along the river, the boat covered the distance between the two piers for 3.2 hours. Find the distance between the two marinas.
1. When the boat moves along the river, its actual speed is the sum of its own speed and the speed of the current. The actual speed of the boat is:
28.3 + 2.6 = 30.9 km / h.
2. Since the actual speed of the boat and the time of its movement are now known, we find the distance between the berths:
30.9 * 3.2 = 98.88 km.
Answer: the distance between the marinas is 98.88 km.
