Question 1207229
<br>
The difference in the positions is 100km; the difference in speeds is 16km/h.  The time required for the Konovalov to overtake Red October is the difference in distances, divided by the difference in speeds: 100/16 = 6.25 hours.<br>
In 6.25 hours at 40km/h, the distance Red October can run is 6.25*40 = 250km.<br>
ANSWER: 250km<br>
