Question

If Maria ran 4 laps of the track at an even pace and it took her 6 minutes to run the first 3 laps, how long did it take Maria to run all 4 laps?

Answer 1

4=x
3=6
6/3=2
2mins for each lap 
so 4=8mins

Answer 2

8 minutes. Because If you divide 6 by 3 it will tell the amount it took her to run one lap and you get 2. So multiply 2 by 4 to get 8. A total of 8 minutes!
