There are 8 Saturday and Sunday in a month. William travels only on Saturdays and Sundays and has flown 1,020 miles this month. <em>He has travelled (1020/8) miles per day = 127.5 miles/day</em>
There are 30-8 = 22 weekdays in a month. Jason travels every weekday and has flown 2,200 miles this month. <em>It would mean that he travelled (2200/22) = 100 miles/day.</em>
It is very clear that no of miles travelled per day by William is more than the no of miles travelled per day by Jason for this month.
