D) 9.92 kilometers

Answer 1

The total distance Julie ran in kilometers is approximately 6.56 kilometers.

Step-by-step explanation:

To find the total distance Julie ran in kilometers, we need to convert each part from different units to kilometers.

First, we convert 1720 meters to kilometers by dividing by 1000: 1720 / 1000 = 1.72 kilometers.

Next, we convert 63580 centimeters to kilometers by dividing by 100000: 63580 / 100000 = 0.6358 kilometers.

Finally, we add up the distances in kilometers: 1.72 + 0.6358 + 4.2 = 6.5558 kilometers.

Therefore, Julie ran a total of approximately 6.56 kilometers.
