Answer 1

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

First, we need to determine how many kilometers are in 1 mile:

1 mile = \( \frac{1}{0.62} \) kilometers.

Now, calculate this:

1 mile ≈ 1.6129 kilometers.

Next, we need to convert Delta's speed of 17 miles per hour to kilometers per hour:

\[ 17 \text{ miles/hour} \times 1.6129 \text{ kilometers/mile} ≈ 27.4 \text{ kilometers/hour}. \]

Therefore, rounded to the nearest tenth, Delta's speed is approximately 27.4 kilometers per hour.

Thus, the correct response is:

27.4
