Question 1207229: The submarine Konovalov, cruising at the rate of 56 kilometers per hour, discovers the submarine Red October 100 km away, moving at a rate of 40 kph. How many kilometers can the Red October run before the Konovalov overtakes it? Answer by greenestamps(13200) (Show Source):
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.
In 6.25 hours at 40km/h, the distance Red October can run is 6.25*40 = 250km.
