$14 m/s$ $14 "m/s"$

Explanation:

From the unit m/s you can see that the wanted answer is the number of meters crossed each second.
therefore
$s p e e d = \frac{distance}{time}$ $speed="distance"/"time"$

It is given that 140 meters are crossed in 10 seconds
Therefore,
$s p e e d = \frac{140}{10} = 14 m/s$ $speed=140/10=14 "m/s"$
