Helga was the fastest clog dancer in all of Slovenia

Helga was the fastest clog dancer in all of Slovenia. With both hands at her sides, she could tap her right foot at a rate of 300 taps per minute, while simultaneously tapping her left foot at a rate of 250 taps per minute. When she raised her arms, her tap rate slowed down to 200 taps per minute with each foot. If she dances a total of 5 minutes, with her arms raised during only 2 of those minutes, what would be the combined total number of times that she taps both of her feet?
