To find Dory's walking rate on the first lap in laps per minute, we start with her given rate of \( \frac{2}{5} \) lap every 4 minutes.
To find her rate per minute, we can set up the calculation as follows:
1. **Rate in laps per minute**:
\[
\text{Rate} = \frac{\text{laps}}{\text{time in minutes}} = \frac{\frac{2}{5} \text{ laps}}{4 \text{ minutes}}
\]
2. **Perform the division**:
\[
\text{Rate} = \frac{2}{5} \div 4 = \frac{2}{5} \times \frac{1}{4} = \frac{2}{20} = \frac{1}{10} \text{ laps per minute}
\]
Thus, Dory's walking rate on the first lap is \(\frac{1}{10}\) laps per minute.
