Question
A boat takes 17 hours to travel from P to Q upstream and from Q to P downstream. If the speed of the boat in still water is 8.5 km/h and the speed of the current is 4.5 km/h, then P and Find the distance between Q.
type-sscSolution
Let the speed of boat in still water =B and speed of stream =S B=8.5km/h, S=4.5km/h Speed of boat in upstream=B-S=4km/h Speed of boat in downstream=B+S=13km/h Let the distance =x ATQ-
