Anton and his friend Jose are playing tag. Anton takes off running at a rate of 7.5 miles per hour. One minute later, Jose starts to chase Anton at a rate of 9 miles per hour. How many miles did it take for Jose to catch Anton?

Anton has a head start     7.5 m/hr * 1/60 hr   

7.5 / 60     miles

 

Jose is running  (9 - 7.5) = 1.5 m/hr faster

       and will close the   7.5/60 miles in        7.5/60 miles  / 1.5 m/hr        hours

 

7.5/60  / 1.5   hours      *    9 m/hr   = .75 mile to catch Anton
