Question
A boat covers some distance downstream in 1 hour. It
covers 3/2 hours. If the velocity of the stream is 3 kilometers per hour, then what will be the velocity of the boat in still water?Solution
15. Let the speed of boat in still water =B and speed of stream =S Given stream =S=3km/h Speed of boat in downstream =B+S, and time =1 hour. Then Distance = (B+S) ×1 Speed of boat in upstream = B-S and time =1.5h Then distance = (B-S) ×1.5 ATQ- (B+S) ×1=(B-S) ×1.5 2B+2S=3B-3S B=5S B=5×3=15km/h
