Solution Steps
Step 1: Determine Initial Distance
The initial distance between Trisha and Josie is calculated as follows:
\[
\text{initial distance} = 3 \, \text{km} - 2 \, \text{km} = 1 \, \text{km}
\]
Step 2: Calculate Relative Speed
The relative speed of Josie with respect to Trisha is given by:
\[
\text{relative speed} = 5 \, \text{km/h} - 3 \, \text{km/h} = 2 \, \text{km/h}
\]
Step 3: Calculate Time to Catch Up
The time it takes for Josie to catch up to Trisha is calculated using the formula:
\[
\text{time to catch up} = \frac{\text{initial distance}}{\text{relative speed}} = \frac{1 \, \text{km}}{2 \, \text{km/h}} = 0.5 \, \text{hours}
\]
Final Answer
The time it took for Josie to catch up to Trisha is \\(\boxed{0.5}\\) hours.
