An observer moving toward Earth with a speed of 0.86 c notices that it takes 4.8 min for a person to fill her car with gas. Suppose, instead, that the observer had been moving away from Earth with a speed of 0.91 c. How much time would the observer have measured for the car to be filled in this case? Express your answer using two significant figures.
