Answer 1

To convert Delta's speed from miles per hour to kilometers per hour, we can use the conversion factor that 1 kilometer is approximately equal to 0.62 miles.

To find the equivalent speed in kilometers per hour, we can set up the following equation:

\[ \text{Speed in km/h} = \frac{\text{Speed in miles/h}}{\text{miles per kilometer}} \]

First, we find how many kilometers are in 1 mile:

\[ \text{miles per kilometer} = \frac{1}{0.62} \] \[ \text{miles per kilometer} \approx 1.6129 \]

Now we can convert 17 miles per hour to kilometers per hour:

\[ \text{Speed in km/h} = 17 \times 1.6129 \] \[ \text{Speed in km/h} \approx 27.4 \]

Therefore, her speed in kilometers per hour is approximately 27.4 km/h when rounded to the nearest tenth.

So the correct response is: 27.4
