Ken's average speed for a trip is 14 miles per hour. During the first part of the trip, he traveled at 15 miles per hour for 2 hours, and then traveled at a different speed for 1 hour the rest of the way. What was her speed for the second part
of the trip?

15 m/h  * 2 hr   +  x m/ *  1 hr

________________________                =     14 m/hr

      2  hr   +   1 hr    

 

 

(15*2 + x  ) / 3    = 14

 

30 + x  = 42

x = 12 m/hr
