Answer:
Keiko completes 4 laps
Abdul completes 3
The total time it takes for them to meet at the starting line is 36 minutes
Explanation:
In order to find how they would meet at the line at the same time, we would need to find a common variable between 9 and 12 (the smallest common Variable)
The smallest variable they both share is 36
9 x 4 = 36
12 x 3 = 36
Hope this helps!
