Find the number of minutes Sebastian swims the whole 12 weeks (45×5)×12 225×12 2700 Sebastian swam 2700 minutes in 12 week. To find the number of laps per hour, Let x be the number if laps per hour 1800/2700=×/60 2/3=x/60 120=3x 120/3=3/3x 40=x Thus Sebastian swam at an average rate of 40 laps per hour.
