It takes John 13 seconds to run 100 meters.  He only goes 4 meters in the first second.  He then maintains the same speed for the rest of the race.  James is 2 m/s faster at the top speed and he can run the first 10 meters in 2 seconds.  How long does it take James to run 100 meters?
How many meters does John run? ** John runs 100-4=<<100-4=96>>96 meters once he reaches his max speed
How many seconds does it take John to run 100 meters? ** He runs it in 13-1=<<13-1=12>>12 seconds
How fast does John run? ** So he runs at a speed of 96/12=<<96/12=8>>8 m/s
How fast is James? ** So that means James's top speed is 8+2=<<8+2=10>>10 m/s
How many meters does James run? ** He has to run 100-10=<<100-10=90>>90 meters at his top speed
How many seconds does it take James to run 100 meters? ** So he runs that at 90/10=<<90/10=9>>9 seconds
How long does it take James to run 100 meters? ** So he takes 9+2=<<9+2=11>>11 seconds to run 100 meters
