Darla flew 75,168 mi in 9yrs to find out how many miles she flew in one year you would divide mi/yr thus 75,168 mi / 9 yr = 8,352 mi/yr

Sonia flew 62,314 mi in 7yrs to find out how many miles she flew in one year you

would divide mi/yr thus 62,314 mi / 7 yr = 8,902 mi/yr

8,902 - 8,352 = 550

therefore Sonia flew the most miles beating Darla by 550 mi/yr
