Vishank Vishank. Solution: Let the speed of the train be x km/h. Downstream speed = (15 + x) km/h. Upstream speed = (15 - x) km/h. Time taken to go 30 km upstream = 30/(15 - x) hrs. Time taken to go 30 km downstream = 30/(15 + x) hrs. According to the Question, ? 30/(15 - x) + 30/(15 + x) = 9/2. Let the speed of the stream be x km/hr. Then, Speed downstream = (15 + x) km/hr Speed upstream = (15 - x) km/hr. We know from question that it took 4(1/2)hrs to travel back to same point. So, (30/15 + x) + (30/15 ? x) = 4(1/2) => / ? x 2 = 9/2 => 9x 2 = => x = 5km/hr. If the boat travels 8 miles downstream in the same time it takes it to travel 4 miles upstream, what is the speed of the current?
