• take the speed of slowest to be = s m/min
  then speed of fastest will be = 2s m/min
  now we know that slowest moves x in 5 min
  so,
  x/s=5
  i.e x=5s
  now in case of fastest he travels 1000+x m to meet the slowest one
  so (1000+x)/2s=5
  as x=5s,
  we solve 1000+5s=10s
  i.e s=200 m/min for the slowest nd for fastest it is 2s i.e 400 m/min
  now total time = 4000/400 = 10 min
