Question
A steamer covers 80 km in 5 hr. in still water. If the
speed of the steamer in still water is 50% more than that of the stream, then time is required for the steamer to cover this distance upstream.Solution
Speed of the steamer in still water = (80/5) =16 km/h Speed of the stream = (16/1.5) = (32/3) km/h Upstream speed of the boat = 16 – (32/3) = {(48 – 32)/3} = (16/3) km Required time taken = 80 ÷ (16/3) = 80 ×3/16 = 15 hours
