A man goes upstream for a distance of 10 km in 5 hours.Another man goes downstream for a distance of 10 km in 3 hrs.What is the difference bw their speed ,if speed of river is 0.5 km/hr?(round answer to two decimal places)

• 10/x-0.5=5, solving we get x=1.5.
  10/x+0.5=3, solving we get x=2.83. So difference b/w speed is 1.33 definetely...

• 0.33km/h.
  speed of man upstream will be 2.5km/h which becomes 2km/h
  speed of man downstream will be 3.33km/h which becomes 2.83km/h
  so difference is 0.33

• Downstream =x+0.5
  Upstream =x-0.5
  0.5+x=(10/5)
  X=1.5
  X-0.5=(10/3)
  X=3.83
  So the difference is 2.33

• speed of upstrem is 2 hrs but river speed is 0.5 .so upstrem speed 2.5 km/hr
  speed of downstrem is 2.83 but river speed 2.83km/hr
  so differnece is 0.33

• ans is 1 bez
  rate of stream=1/2*(rate of downstream-rate of upstream)
  0.5*2=1

• 1.33kmh

• speed of river=0.5km/hr
  speed of man upstream=10/5=2km/hr
  net speed upstream=2-0.5=1.5km/hr
  speed of man downstream=10/3=3.33km/hr
  net speed downstream=3.33+0.5=3.83
  So diff. in speed=3.83-1.5=2.33

• ans- 0.33 km/h.
  suppose
  u=speed of man
  v=speed of river (0.5km/h)
  A goes upstream so u-0.5=10/5=5/2
  Another goes downstream so u+0.5=10/3=17/6
  difference between their speed= 17/6-5/2=1/3=0.33

• the difference in their speed is 20/15=2*speed of river +actual difference in speed
  therefore actual difference in their speed is=20/15-1= 0.33 km/hr

• 10/5=2 i.e the speed of man going upstream=2 km/hr.
  river must have oppose the velocity, ( x-0.5)=2 therefore speed of man=2.5k/hr
  
  10/3=3.33 i.e the speed of another man going downstream=3.33km/hr
  river must have supported the velocity,(x1+0.5)=3.33,therefore speed of ANOTHER man=2.83
  therefore actual difference in their speed =2.83-2.5=0.33km/hr

• s=d/t
  for upstream, 0.5-x=10/2
  x=1.5
  for downstream, 05+y=10/3
  2.83
  so difference is=1.33

• Let us Know S=D/T;
  1) S1= 10/5 = 2
  2) S2= 10/3 = 3.33
  S2 - S1 = 3.33 - 2 = 1.33
