An interstellar cruise ship races by a Martian spaceport. According to galactic regulations, the safety strobe lights on the ship's bridge are assumed to blink every 1.50 seconds. A rookie policemartian, based on the planet, issues a ticket, claiming he measured the time interval among blinks as 1.79seconds. You are called upon by the indignant captain to describe the discrepancy, who maintains that her lights are fully compliant by code. What spacecraft speed will show both the captain and policemartian to be right?
