Using proprietary software hacked from the NSA, I was able to tremendously enlarge a second photo that shows more of the bridge without losing any clarity. This allowed me to identify the make and model of every vehicle on the bridge to identify their lengths. (Okay, that’s not true — I used Adobe Fireworks to measure the cars in pixels, and looked up the length of an average passenger car. It just sounded cooler the other way.)
In any case, the average car is 14 feet long, and the average length of the cars I could measure on the bridge was 34.4 pixels. The length of the bridge is 2,709 pixels. How long is that span in feet? (Hint: Set up a proportion that compares photo length in pixels to actual length in feet for cars on one side of the equation, and the bridge on the other.)
