Put the attention to amount of time instead of points in time. The distance from home to school is d. The time each travels until meeting is t.
____________________speed________time__________distance
Peter______________d/20___________t____________d=(d/20)t
Mom________________d/6____________t____________d=(d/6)t
, the total of their traveled distances must be d. Seeing that left and right sides have the same factor of d, you can solve the equation for t. MINUTES.
