jamie ran two laps around a track in 99 seconds. how long did it take him to run each lap if he ran the first lap 8.5m/s and the second at 8.0m/s?

Let t be the first lap time and L be the length of one lap.

8.5 m/s * t = L

8 m/s * (99-t) = L

These two equations in two unknowns can be solved for both L and t.
