. Scott starts jogging from point X to point Y. A half-hour later his friend Garrett who jogs 1 mile per hour slower than twice Scott’s rate starts from the same point and follows the same path. If Garrett overtakes Scott in 2 hours, how many miles will Garrett have covered?
a) 11/5 b) 10/3 c) 4 d) 6 e) 20/3

• let scott speed be x m/hr
  garrett speed (2s-1) m/hr
  distance covered by scott in 2.5 hrs= (5/2)s m/hr
  distance covered by garrett in 2 hrs = 2(2s-1) m/hr
  (5/2)s= 2(2s-1) m/hr
  solving above we get
  s=(4/3) m/hr
  garret speed = 5/3 m/hr
  so in 2 hr distance covered will be 10/3 miles

• 1/2*x + 2*x = (2x-1)*2
  x=4/3
  so the ans is b
