To find Delta's speed in kilometers per hour, we need to convert her speed from miles per hour to kilometers per hour.
Given that 1 kilometer is approximately equal to 0.62 miles, we can set up a proportion to solve for Delta's speed in kilometers per hour.
Let x be the speed in kilometers per hour.
17 miles per hour = x kilometers per hour
Now, we can set up the proportion:
17 miles per hour / 0.62 miles = x kilometers per hour / 1 kilometer
Cross-multiplying, we get:
17 miles per hour * 1 kilometer = x kilometers per hour * 0.62 miles
17 kilometers = 0.62x
Now, to solve for x, we can divide both sides of the equation by 0.62:
17 kilometers / 0.62 = x
Approximately, x = 27.4 kilometers per hour.
Thus, Delta's speed in kilometers per hour is approximately 27.4 kilometers per hour.
The answer is 27.4.
To convert the speed from miles per hour to kilometers per hour, we need to multiply by the conversion factor. The conversion factor is 0.62 miles per kilometer.
17 miles per hour * 0.62 miles per kilometer = 10.54 kilometers per hour
Rounded to the nearest tenth, Delta's speed is 10.5 kilometers per hour. So the correct answer is O 10.5.
To find Delta's speed in kilometers per hour, we need to convert the speed from miles per hour to kilometers per hour using the conversion factor given (1 kilometer ≈ 0.62 miles).
First, we'll convert Delta's speed from miles per hour to kilometers per hour.
Delta's speed in miles per hour: 17 miles per hour
Now, we'll use the conversion factor to convert miles to kilometers:
17 miles per hour × 0.62 kilometers per mile ≈ 10.54 kilometers per hour
Rounding to the nearest tenth of a kilometer gives us Delta's speed in kilometers per hour as approximately 10.5 kilometers per hour.
Therefore, the correct answer is:
10.5
