This is more logical ...

Let the 1st flag 1 placed at the origin ....
in crossing 8 flags he traveled 7 distances....
s=d/t
=7/8

time for 4 flags t=(d/s)=4/(7/8)=(4*8)/7=4.5714285714285714285714285714286

let the 1st flag i placed at the origin and the remaining on the X-axis.......then the cordinate og 8th flag is (7,0)..therefore distance travelled is 7 units in 4 second ......and cordinate of 12th flag is (11,0)..there r 4 units ....so tym taken is (8*4)/7=4.57 secnds

et the 1st flag i placed at the origin .... in crossing 8 flags he traveled 7 distances.... in 8 secs , So to travel 1 flag time required : 8 / 7
for 4 more flags time required : (4) * (8 / 7)= 4.5714285714285714285714285714286
