Question 634188: Nancy and Mark commute to work, traveling in opposite directions. Nancy leaves the house 8:00am and averages 35 miles per hour. Mark leaves at 8:15am and averages 40 miles per hour. At what time will they be 140 miles apart? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! 35*(x+1/4)+40x=140
x=7/4 or 1 3/4 hours from 8:15.
So at 10:00 am they will be 140 miles apart.
