Ben and Jerry start out one thousand miles apart If Ben drives toward Jerry at sixty-five mph and Jerry drives toward Ben at forty-six mph how far apart will they be after four hours?

distance apart = 1000 - Jerry's distance in 4 hours - Ben's distance in 4 hours

d = 1000 - 4(65) - 4(46) = 1000 - 260 - 184 = 1000 - 444 = 556 miles.
