The average rate was 40 laps per hour

Explanation:

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
