10.5

17.6

27.4

Answer 1

To convert miles to kilometers, we can multiply the given speed of 17 miles per hour by the conversion factor of 0.62 kilometers per mile:

17 miles/hour * 0.62 kilometers/mile = 10.54 kilometers/hour

Rounded to the nearest tenth of a kilometer, Delta's speed is approximately 10.5 kilometers per hour.

Therefore, the correct answer is 10.5.
