To convert miles to kilometers, we need to divide the number of miles by the conversion factor, which is 0.62.
So 17 miles is equal to 17/0.62 = 27.4 kilometers.
Rounded to the nearest tenth of a kilometer, her speed is 27.4 kilometers per hour.
Therefore the correct answer is 27.4.
To convert miles per hour to kilometers per hour, you can use the conversion factor of 1 kilometer is approximately equal to 0.62 miles.
To find Delta's speed in kilometers per hour, you can multiply her average speed of 17 miles per hour by the conversion factor:
17 miles/hour * 0.62 kilometers/mile = 10.54 kilometers/hour
Rounded to the nearest tenth of a kilometer, Delta's speed in kilometers per hour is 10.5 kilometers/hour.
Therefore, the correct answer is 10.5.
To find Delta's speed in kilometers per hour, we need to convert her average speed from miles per hour to kilometers per hour.
We know that 1 kilometer is approximately equal to 0.62 miles.
To convert from miles to kilometers, we can use the following formula:
Speed in kilometers per hour = Speed in miles per hour * Conversion factor
In this case, the conversion factor is 0.62.
So, Delta's speed in kilometers per hour can be calculated as:
Speed in kilometers per hour = 17 miles per hour * 0.62
Speed in kilometers per hour ≈ 10.54 kilometers per hour
Round to the nearest tenth of a kilometer:
Speed in kilometers per hour ≈ 10.5 kilometers per hour
Therefore, the correct answer is 10.5 kilometers per hour.
