27
Step-by-step explanation:
Let's set this up as an equation.
We know that dividing with exponents means we subtract the exponents. 15-12 = 3.
Let's say that d is distance, and the formula is as follows;
d=
This means that with the values filled in we have an equation that looks like;
Therefore solving would look like;

1 lap in 2.5 minutes
so 4 in 10 minutes and 12 in 30.
Also 0.4 laps in 1 minute
