Step 1: Calculate the total number of 12-hour intervals in 14 days. First, determine the total number of hours in 14 days, and then divide that by 12 hours to find the number of intervals. The number of hours in 14 days is: 14 days×24 hours/day=336 hours The number of 12-hour intervals is: 336 hours12 hours/interval=28 intervals Step 2: Calculate the total time the watch goes fast.

Total minutes fast: 28 intervals×3 minutes/interval=84 minutes Step 3: Convert the total minutes to hours and minutes. To convert the total minutes into hours and minutes, divide by 60. 84 minutes=8460 hours=1 hour and 24 minutes Answer: The watch will go fast by 1 hour 24 minutes in 14 days.
