How would you explain this question in your head then try to solve your way. I hope this helps you with the question.
To solve this, we first have to find an individual rate:
3/5
4/7
For the first one:
1 lap in 5/3 minutes
Second one:
1 lap in 7/4 minutes
find a common LCD
5/3 and 7/4
20/12 and 21/12
4 laps in 7 minutes is faster
