To estimate the distance from New Jersey to California using a scale bar, you would typically look for the length indicated on the scale and compare it to the distance represented on a map. Since I can't see the image you're referencing, I can provide a general approximation.
The distance from New Jersey to California is often reported to be around 2,500 to 3,000 miles, depending on the specific locations chosen (for example, from Newark, NJ to Los Angeles, CA).
From the options you've provided, the closest estimate would likely be "About 1600 miles," though this is significantly less than the typical distance. If you're looking at a map where the scale indicates something different, please refer to that for a more accurate estimate based on the scale provided.
