12 Laps can be done in 48 minutes
Here is a question about rate and proportions
From the question, we have that 1 lap took 4 minutes
Thus, the number of laps we can have in 48 minutes will be the obtained by dividing it by the time it took for one lap
Mathematically, we have this as;
[tex]\frac{48\text{ minutes}}{4\text{ minutes/lap}}\text{ = 12 laps}[/tex]
