Solution: A boat moves through the water of a river at 15.8 m/s relative to the water, regardless of the boat’s direction. If the current is flowing at 13.2 m/s, how long does it take the boat to complete a trip consisting of a 186 m displacement downstream followed by a 448 m displacement upstream?1. 454.8532. 61.04223. 89.24634. 219.4235. 79.84426. 178.7217. 77.42868. 559.8229. 41.670710. 225.913
