Question

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?

Answer 1

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
 Answer:
 his average rate in laps per hour is:
 40 laps / hour
