A boat travelled 8km upstream in 30 minutes and 6 km downstream in 15 minutes. Then in how long it will take to go 12 km in still water?
ATQ, we can say that The speed of boat will travelling to Upstream is = (8/30)/60 = 16km/hr The speed of boat will travelling to Downstream is = (6/15)/60 = 24km/hr Then Speed of boat in still water will be = (16 + 24)/2 = 20 km/hr Hence, the Required time will be = (20 /12)hr = (12/20) x 60 min = 36 min
