To convert the speed from miles per hour to kilometers per hour, we can use the proportion:
1 kilometer / 0.62 miles = x kilometers / 17 miles
Cross-multiplying, we get:
0.62x = 1 * 17
0.62x = 17
To solve for x, divide both sides of the equation by 0.62:
x = 17 / 0.62
x ≈ 27.42
Rounded to the nearest tenth of a kilometer, Delta's speed in kilometers per hour is 27.4 km/h.
Therefore, the correct answer is 27.4.
