Question
A Submarine undertakes a journey, covering a distance of
44.8 km against the current in precisely 2 hours and 48 minutes. The challenging task at hand is to determine the Submarine's speed when there's no current (in still water), given that the ratio of its upstream speed to downstream speed is 4:7.Solution
ATQ, Speed of Submarine in upstream = 44.8/2.8 = 16 km/h Speed of Submarine in downstream = 16/4 × 7 = 28 km/h Speed of Submarine in still water = (16 + 28)/2 = 22 km/h
