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

He swam 1,800 laps total in 12 weeks. Each week, he swam 150 laps because 1800/2=150 in 5 days. Each day, he swam 30 laps because 150/5=30, in 45 minutes. His average time was 30/45=2/3 At that rate, in one hour, he would swim 2/3*60 = 2/3 x 60 = 40 laps/hour Final answer is 40
