Regan's New Year's resolution is to exercise more. Today, she plans to run 1.5 miles on the track around her school's football field. If each lap around the track is 0.25 miles, how many laps should she run?

To find the number of laps Regan should run, we divide the total number of miles she plans to run by the number of miles per lap: 1.5 miles / .25 miles per lap = <<1.5/.25=6>>6 laps. Answer: \boxed{6}.
