Hi Dawn;
It is a great answer.  While I realize you are much more qualified than I am, it is my understanding that the 12 minutes must be converted to hours to be consistent with the fact that the cyclists are traveling at 10 and 16 miles/hour.  Or, the speeds must be converted to miles/minutes.
10 mph * time, and 16 mph * (time - 12)
The 12 minutes must be converted 0.2 hours.
Is that correct?
