Question
Speed of a boat in downstream is 50% more than that in
upstream. Total time to travel 48 km upstream and 36 km downstream is 6 hours. What is the speed of boat in downstream?Solution
Speed of a boat in downstream = 150/100 × Speed of a boat in upstream DS : US = 3x : 2x According to question, => 48/2x + 36/3x = 6 => 144 + 72 = 36x => x = 6 Speed of a boat in downstream = 3x = 3 × 6 = 18 km/hr
