While planning their outing,abhishek understood that their boat could travel with a speed of 12kmph in still water.The group decided to travel 24 minutes downstream.Aarti had prior experience in that route and mentioned that the speed of stream was 4kmph.How many kms will the group travel downstream?
a)6.4 b)3.2 c)4 d)4.8

• speed of boat in downstream=12+4=16km/h
  ANS:=
  distance=16*24/60=6.4km

• Speed of boat in Downstream=speed of boat in still water+speed of stream
• 7 years agoHelpfull: Yes(1) No(0)
• speed of boat travelling downstream=speed of boat in still water+speed of stream
  a=12+4
  a=16kmph
  a=16*5/18mps
  a=40/9mps
  
  kms group will travel downstream=a*24*60m
  = 6400m=6.4km

• Downstream =speed on still water-stream speed
  So downstream =8
  Distance=(24/60)*8=3.2km
