Answer:

  yes, after 52 minutes

Step-by-step explanation:

If t represents the time in minutes each person is working after Sheila arrives, then the number of parts produced is ...

  Eric: 156 +12t

  Sheila: 15t

These values are equal when ...

  156t +12t = 15t . . . . . Eric's part count is equal to Sheila's part count

  156 = 3t . . . . subtract 12t

  52 = t . . . . divide by 3

Sheila will catch up to Joe after 52 minutes.
