<human>:  James decided to walk to the store. When he got halfway there he realized he forgot something at home and had to walk back. If his home is 4 miles from the store and he walks 4 miles per hour how long did it take him to reach the store?
<bot>: How far did James walk before turning around? ** He walked 4/2=<<4/2=2>>2 miles there before turning around
How many miles did James walk in total? ** So in total he walked 2+2+4=<<2+2+4=8>>8 miles, he walked 2 miles to the halfway point than 2 miles home.
How long did it take James to reach the store? ** That means it took him 8/4=<<8/4=2>>2 hours
