We know the speed of the raft (20.4 kilometers) and time (6 hours), therefore we can find the speed: 20.4 / 6 = 3.4 (km / h) – the speed of the raft. Knowing these data, we can calculate the time for which the raft will swim at a speed of 25.5 km: 25.5 / 3.4 = 7.5 (hours) – he will swim.
Answer: 7.5 hours
