A man goes upstream for 10 km in 5 hour .another man goes downstream for 10 km in 3 hour .if speed of stream is 15 km/h what is the difference in speed of both men.

• speed in upstream = 10/5 = 2 kmph
  speed in downstream = 10/3 kmph
  upstream = 15-2 = 13 kmph
  downstream = 15+10/3 = 18.33 kmph
  18.33-13.00= 5.33

• speed in upstrem=10/5=2km/hr speed in downstream=10/3
  in upstream =15-2=13km/hr in downstream=15+10/3=18.33
  18.33-13.00= 4.67 ans

• Upsteam
  D= T*S
  10=3*(B-15)
  =>B=17
  Similarly Downstream
  10=3*(B+15)
  B=11.66
  Diff in speed= 17-11.66= 5.34

• 28.6
  (x+15)3=10
  x=-11.6
  (y-15)5=10
  y=17
  x-y=28.6

• the question is wrong. when the speed of the stream downstream is 15 km per hour, how does the person take 3 hours to cover 10 km? he will cover 15 x 3 + his speed for 3 hours distance. so the data is wrong

• in case of upstream,
  speed of man=x
  x-15=10/5
  x=17
  in case of downstream,
  speed of man=y
  y+15=10/3
  y=55/3
  diffrence of speed=y-x
  55/3-17=1.3333
