<human>:  It takes 20 minutes for John to go to the bathroom 8 times. How long would it take to go 6 times?
<bot>: How many minutes does John spend each time he goes in? ** He spends 20/8=<<20/8=2.5>>2.5 minutes each time he goes in
How many minutes would it take to go 6 times? ** So it would take 2.5*6=<<2.5*6=15>>15 minutes to go 6 times
