Question
Speed of a boat in still water is 10 km/hr. If speed of
stream is 2 km/hr, then how much distance can the boat travel downstream is 2.5 hours? type sscSolution
let the Speed of boat in still water =B and speed of stream =S B=10km/h, S=2km/h Speed of boat in down stream B+S=12km/h Speed of boat in upstream B-S =8km/h in 2.5 h boat complete distance in downstream =2.5×12=30km
