Problem of the Week, 9/17/10: “Flying Flora”

Flying Flora, late as usual for her business meeting, speeds from Santa Fe to Las Cruces at 105 mph.

After arriving in Las Cruces, she gets an email alerting her that she was caught by a radar gun and received a speeding ticket (she knows the local DA; otherwise she would have been thrown in jail!). Much chastened, Flora drives back from Las Cruces to Santa Fe at just 60 mph.
