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
1 is 5/5 for slope for the second one i’m not sure
I am pretty sure it is D.
All the other ones don't affect the second activity...
Hope I helped...
