How many hours did John spend swimming? ** He spent 6/2=<<6/2=3>>3 hours swimming
How many hours did John spend watching shows? ** He spent 3*2=<<3*2=6>>6 hours watching shows
How many hours did John spend on these activities? ** So he spent 6+3+6=<<6+3+6=15>>15 hours on these activities
How many hours did John spend on activities? ** That means he spent 15/.3=<<15/.3=50>>50 hours on activities
How many hours did John spend sightseeing? ** So he spent 50*.4=<<50*.4=20>>20 hours sightseeing
