4.8627 cubic centimeters of birch, 3.91653 cubic centimeters of maple, and 8.44371 cubic centimeters of pine.
...obviously.....
If Train A is traveling at 40 mph and train B is traveling at 50 mph train a passes station at 2:15am and train b passes the station at 2:45am what time will train b catch up to train a if same direction accounting for an average wind speed of 40 mph in an eastward direction. Train A leaves the station, accelerating up to 20m/s in 2 minutes, after which it reaches an average speed within 18 minutes 32 seconds while train B accelerates up to 20m/s in 2 minutes before averaging within 16 minutes 44 seconds. The distance between them, however, is reducing by 35 + 45 = 80 miles per hour. If there is 600 miles of track between them to start out with, it will disappear in 600/80 = 7.5 hours. In exactly how many minutes and seconds does it take before you actually stopped reading this entire equation and thought it was complete nonsense?
