To find 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 seconds).
Plugging in the values:
\[ v = \frac{10 \text{ m}}{5 \text{ s}} = 2 \text{ m/s} \]
So, Mrs. Wade's velocity is 2 m/s.
The correct answer is d 2 m/s.
