Four cracks per second. With the information given in the question, it's not possible to determine a true 'speed' because no distance information is given. If the cracks were 3-ft apart, then his speed was 12 ft per second, or about 8.2 mph. But this is only an example. It can't be assumed, since sidewalk blocks are not standard throughout the US. In general, if 'B' is the length of the sidewalk blocks, then the skater's speed was == 4Bfeet per second == 2.72B miles per hour
