You have 2 photos of a bicyclist. One shows the rider at the corner of Third and Main streets, the other shows the rider at Twentieth and Main. There are lampposts at every corner in this town, and the first picture shows it to be 10:32:00 exactly. The second picture shows it to be 10:41:20. You know three facts: 1). All of the clocks are synchronized; (2) there are exactly 12 equal sized blocks per kilometer in this town; and (3) the streets that cross Main in this area are numbered consecutively, with no interruption. (a) How many blocks did the bicyclist cover? (b)How many km did the bicyclist cover? (c) How many seconds did it take the cyclist to cover this distance? (d) How many hours does this represent? (e) What is the bicyclist's average speed in km/hr?
