he can swim 3 laps in 7 minutes.
28÷7=4
4*3=12
we can conclude that in 28 minutes he can swim 12 laps.

Jack can swim 12 laps in 28 minutes. 28 minutes is 4 times greater than the time it took him to swim 3 laps. With 28 minutes he should therefore be able to swim 4 times as many laps. 3 times 4 equals 12
