Sebastian swam 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 1,800 laps.What was his average rate in laps per hour?

Answer 1

45x5 = 225 minutes a week

225 x 12 = 2700 minutes in 12 weeks

2700 / 60 = 45 hours

1800 / 45 = 40 laps per hour

answer: average 40 laps per hour

Answer 2

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.
