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
