Sebastian swan laps every day in the community swimming pool. he swam 45 minutes each day, 5 days each week, for 12 weeks. in that time, he swam 1800 laps. what was his average rate in laps per hour?

The first thing we must do for this case is find the amount of minutes we have then:
 "45 minutes each day, 5 days each week, for 12 weeks":
 (45) * (5) * (12) = 2700 minutes.
 We consider the following conversion:
 1 hour = 60 minutes.
 Therefore the number of hours is:
 (2700) * (1/60) = 45 hours
 Finally the average rate in laps per hour is:
 Average = (1800) / (45)
 Average = 40 laps / hour
 
 his average rate in laps per hour is:
 40 laps / hour

Lol idk ask google. ejie
