2. After robbing a bank in Dodge City, a robber gallops off at 15 mi/h. 20 minutes later, the marshall leaves to pursue the robber at 15 mi/h. How long (in hours) does it take the marshall to catch up to the robber?
Answer provided by our tutors
the Marshall will never catch up to the rubber since they move with the same speed of 15 m/h and the robber has a constant advance of (20/60)*15 = 5 mi.
