12 minutes to drive 30 laps and 48 minutes to drive 120 laps are they equivalent

If they are equivalent, you should be able to cross multiply and get a true statement.

12/30 = 48/120

12 (120) = 30 (48)

1440 = 1440

This is a true statement, therefore they ARE equivalent.

30/12=in 1 min you drive 2.5lap

120/48=in 1 min you drive 2.5lap

yes they are equivalant
