The average rate was 40 laps per hour

First we want to figure out how many minutes he swam in one week

45 min a day for 5 days
$45*5=225$

So he swims 225 minutes every week, for 12 weeks
$225*12=2700$

Now we want to convert minutes to hours
$2700/60=45$

So it took him 45 hours to swim 1800 laps
Laps per hour signifies division, laps over hours

$1800/45=40$

40 laps per hour
