Simplify using factors: \( \frac{2 a-2 b}{-a+b} \)

A sprinter runs around a 400 m running track twice (distance \( =800 \mathrm{~m} \) ). They start in lane 1 and finish in lane 1 (start and finish in the same position). They complete the run in 2 min 20 sec . Calculate their average velocity (not speed!) and include the unit \( (\mathrm{m} / \mathrm{s}) \) ?
