Answer 8

\[\sf \frac{5.067 km}{61 laps} \rightarrow \approx \frac{8.31 \times 10^{-2} km}{1 lap} \times \frac{1mi}{6.21 \times 10^{-1}km} \times \frac{1 hr}{225 mi} \times \frac{60min}{1hr}\approx \frac{xmin}{lap}\]

Answer 9

units cancel and convert properly

Answer 10

kilometers cancel out, miles cancel out, then the hour is converted into minutes
so basically you are left with minutes per lap unit

Answer 11

the question is how long will it take to go around once
that is hour/lap

Answer 12

or min/lap or sec/lap
depends on what you want, but it should be time/lap
