From his home, Sam would have to walk 5 miles north to get to his friend Hayley's house and 1 mile east to get to his friend Lexi's house. One day, Sam walked from his home to Lexi's house. Together, Lexi and Sam cut directly through the field that separated them from Hayley's house. When they finished playing at Hayley's, Sam walked back home. In all, how far did Sam walk? If necessary, round to the nearest tenth.​
