. Two persons start at the same point, walk in opposite directions with 5 km/hr and 5.5 km/hr respectively.
What is the distance separated after 2 and half hrs?

• Ans. 26.250 km.
  
  As the two persons are moving in the opposite direction, so they will be separateed in 1 hour = 5 + 5.5 = 10.5 km.
  
  They will be separated in 2.5 hours = 10.5 * 2.5 = 26.250 km

• Let a walk at speed of 5 km/hr
  and b walk at speed of 5.5 km/hr
  In 2 1/2 hour,a-12.5km
  b-13.75km
  so, the distance is 12.5+13.75=26.25km

• d=s*t
  d=(5+5.5)*2.5
  d=26.25km

• two person , suppose A and B
  A will cover 12.5km distance ( 5km in one hour , 10 in 2 hour , nd 12.5 in 2.5 hour)
  B will cover 13.75 km
  add both distance we get
  12.5+13.75=26.25
  ans = 26.25

• ans is10:11
  (5*2.5)=12.50 & 5.5*2.5=13.75 now12.50:13.75=10:11

• 26.25 km because one person travels a distance of 13.75 km and other 12.5 km. so totally it is 26.25 km

• 1st Case: 5km --> 1Hr (5km covered in 1hour i.e 5km/hr)
  or 1hr --> 5Km (thats the same thing)
  So in 2.5 hours person covers , (apply unitary method)
  = 2.5 X 5 = 12.5 km
  2nd Case : Similarly 1hr--> 5.5 km
  So, in 2.5 hours ,person covers = 5.5 x 2.5 = 13.75 km
  So, distance they are separated = 12.5 + 13.75 = 26.25 km

• ans:26.25km
  d=d1+d2
  d1=5(5/2)
  d2=5.5(5/2)
  d=(25/2)+(27.5/2)
  =26.25 km

• 1st person covers 5*2.5=12.5km
  2nd person covers 5.5*2.5=13.75km
  so distance separated b/w two is 26.25km
