To convert Angie's speed from miles per hour to kilometers per hour, we can use the conversion factor given that 1 km is approximately 0.62 miles.
First, we need to find out how many kilometers are in 1 mile:
\[ 1 \text{ mile} \approx \frac{1}{0.62} \text{ km} \approx 1.613 \text{ km} \]
Now, we can convert Angie's speed of 17 mph to kilometers per hour:
\[ 17 \text{ mph} \times 1.613 \text{ km/mile} \approx 27.472 \text{ km/h} \]
Now we round this to the nearest tenth:
\[ 27.472 \text{ km/h} \approx 27.5 \text{ km/h} \]
Therefore, Angie's speed in kilometers per hour is approximately 27.5 km/h.
