b. 7.42 kilometers
c. 9.92 kilometers
d. 9.42 kilometers

Answer 1

Julie ran a total of approximately 6.56 kilometers in three parts.

Step-by-step explanation:

To find the total distance Julie ran in kilometers, we need to convert each part of the run to kilometers and then add them together. First, we will convert 1720 meters to kilometers by dividing it by 1000:

1720 meters ÷ 1000 = 1.72 kilometers

Next, we will convert 63580 centimeters to kilometers by dividing it by 100,000:

63580 centimeters ÷ 100,000 = 0.6358 kilometers

Finally, we add up the three distances:

4.2 kilometers + 1.72 kilometers + 0.6358 kilometers = 6.5558 kilometers

Rounded to two decimal places, Julie ran a total of approximately 6.56 kilometers.
