Question
The speed of a boat downstream is 20% more than the
speed of the boat in still water. If the boat can travel 1280 km upstream in 16 hours, then find the distance traveled by the boat in 12.5 hours downstreamSolution
Let the speed of the boat be 100 km/h Speed of boat in downstream = 1.2 × 100x = 120x km/h Speed of boat in upstream = 100x – 20x = 80xkm/h According to the question. 80x =1280/16 = 80 x = 1 Desired distance = 120 × 12.5 = 1500 km
