The time taken to stuff and seal 63 envelopes by both Tom and Jerry will be 6 minutes.

Given the Parameters :

  • Jerry's rate = 15/2 = 7.5 envelopes per minute
  • Tom's rate = 3 envelopes per minute

Combined rate :

  • Jerry's rate + Tom's rate
  • 7.5 + 3 = 10.5 envelopes per minute

Time taken if they work together :

  • Total number of envelopes = 63
  • Total time taken = total number envelopes ÷ combined rate
  • Total time taken = (63 ÷ 10.5) = 6 minutes

Therefore, the time taken of they both worked together will be 6 minutes
