Question 1197146
<font color=black size=3>
It appears the distances are cutting in half each time.


If so, then first six terms are
4000, 2000, 1000, 500, 250, 125


Total Distance = 4000+2000+1000+500+250+125 = 7875 meters = <font color=red>7.875 km</font>


Divide by 1000 to go from meters to kilometers.
