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. This means:

\[ 1 \text{ mile} \approx \frac{1}{0.62} \text{ kilometers} \]

Calculating this gives:

\[ 1 \text{ mile} \approx 1.6129 \text{ kilometers} \]

Now, to convert 17 miles per hour to kilometers per hour, we multiply by the conversion factor:

\[ 17 \text{ miles per hour} \times 1.6129 \text{ kilometers per mile} \approx 27.4 \text{ kilometers per hour} \]

Thus, rounded to the nearest tenth, Delta's speed in kilometers per hour is:

27.4
