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
