Satellites and satellite images

Julie:
You said one image was approximately 10,000 square kilometers. Imagine that great-grandfather lost the treasure somewhere between Anchorage and Nome. This is about 1,800 kilometers. Let us say he could have gone about 100 kilometers away on either side of the main track. Then we will need to search an area of 360,000 square kilometers. We need to see at least 36 images.
Tim:
Wow! That was great. You should be a mathematician.
Julie:
But, I already am.
