1 answer

The first step is to convert kilometers to meters: 3.5 km = 3,500 meters.

Now, we add the total distance they ran in meters:
3,500 meters + 4,200 meters = 7,700 meters.

Finally, we convert meters to centimeters: 7,700 meters = 770,000 centimeters.

Therefore, the total number of centimeters Omar and Paula ran is 770,000 centimeters, which is not one of the options provided.
