Key here is that Roger has already ran for 1 minute at 1/8 miles per minute. He has gone 1/8 of a mile. May be easier to think of the route as a position path. When will Roger and Jeff reach the same position? TIME is the variable to solve for. You'd use expressions of distance but you're not really looking for distance. \r
