A certain distance is covered at a certain speed. if half of the distance is covered in double the time the ratio of the two speeds is

• 4:1
  
  Let 'd' be the initial distance , 's' speed and 't' time taken.
  
  d2 = d/2
  t2 = 2t
  s2 = d2/t2
  =d/4t
  
  s/s2 = (d/t)/(d/4t)
  =4/1
  
  s:s2 = 4:1

• ratio will be 4:1.

• s=v1/t
  s/2=v2/2t
  v1/v2=14:1
