  PROBLEM 11.CQ1 
  A bus travels the 100 miles between A and B at 50 mi/h and then another 
  100 miles between B and C at 70 mi/h. The average speed of the bus for the 
  entire 200-mile trip is: 
  (a) more than 60 mi/h 
  (b) equal to 60 mi/h 
  (c) less than 60 mi/h 
   
  SOLUTION 
  The time required for the bus to travel from A to B is 2 h and from B to C is 100/70 = 1.43 h, so the total time 
  is 3.43 h and the average speed is 200/3.43 = 58 mph.
