Solve the equation. (Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.) \[ 25 x^{3}-125 x^{2}-25 x+125=0 \] \( x=\square \)

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 \( (\mathrm{m} / \mathrm{s}) \) ?

Put the following values into ascending order: \[ \frac{18}{7}, \quad 2 \frac{3}{5}, \quad \frac{23}{6}, \quad 1 \frac{5}{8} \]
