To calculate Mrs. Wade's velocity, you can use the formula:
\[ v = \frac{d}{t} \]
where:
- \( v \) is the velocity,
- \( d \) is the distance (10 m),
- \( t \) is the time (5 s).
Now, plugging in the values:
\[ v = \frac{10 , \text{m}}{5 , \text{s}} = 2 , \text{m/s} \]
So, the correct answer is:
d 2 m/s.
